Rectal prolapse occurs when the rectum, which is the last part of the intestines, gets turned inside out (everted), and sticks out of the anus. It looks like a red or pink tubular structure sticking out of the area from which your pet normally poops. It can also be crusty, ooze, or be a dark color if it has been around for a while. Rectal prolapse is not the same thing as hemorrhoids, which are swollen veins from the rectum that bulge out of the anus.

Why a Prolapse Happens 

Prolapse can occur after a pet has been straining to poop for a while. Some of the most common reasons this can happen is if the pet has intestinal worms, is dehydrated, constipated, has diarrhea or loose stool, or has an intestinal blockage such as a tumor or has eaten an object that he is having trouble passing. Over time, straining leads to weakening of the structures that keep the rectum in place, causing the rectum to stick out through the anus. 

Other Symptoms 

If your pet has a rectal prolapse, you may also have noticed that he has been spending a lot of time trying to poop recently. An example of straining is standing in the classic, “hunched” posture used for emptying the bowels for longer than usual. It can also mean pooping more times than usual, even if he is able to finish quickly. You may also have seen an unusual change in the poop, such as being small and dry, looser than usual, or covered in intestinal worms. If you haven’t noticed any change in regular habits, either because keeping an eye on your pet’s bathroom habits is gross or because you have a sneaky pet that hides in order to go, it isn’t a big deal. Your veterinarian will know what to do. 

Diagnosing a Rectal Prolapse 

To officially diagnose a rectal prolapse, your veterinarian will give a pretty thorough physical examination, including a rectal exam in which they feel the prolapsed tissue. A fecal sample will likely be taken to check for worms and other intestinal issues. If a blockage is suspected, x-rays and/or an abdominal ultrasound may be necessary. 

Treatment 

To treat the prolapse, the vet will have to carefully clean the area before replacing it back into its original position. If it is swollen, additional medications or solutions may need to be applied to shrink the prolapse. Sometimes sedation or anesthesia is needed because a prolapse can be painful, especially if it becomes infected. 

If the prolapse can be replaced, the vet may tie a “purse-string” suture around the anus to keep the opening small and prevent the rectum from prolapsing again. This fix is temporary until your pet heals. The suture will need to be removed later (your vet will tell you when), but it is important that you don’t let your pet chew the area or the suture may break. Antibiotics and pain medications may be sent home, as well as an e-collar, to ensure the rectal tissue heals properly. 

Occasionally, a rectal prolapse cannot be replaced, or the tissue is too damaged. In these cases, surgery will be necessary to either remove the damage tissue (called a resection and anastomosis) or tack the rectum into the body wall from inside the abdomen (called a colopexy). 

In addition to treating the prolapse, your veterinarian will also want to treat the cause of the prolapse (e.g., treat for intestinal worms). Stool softeners may also be prescribed for a short period to keep your pet from straining. Most pets improve and do not continue to have issues once the rectal prolapse heals. If you have any questions or concerns about your pet’s diagnosis and treatment, give your vet a call so they can guide you further.

ake-Homes for Pet Diabetes:

1. Diabetes mellitus is caused by a deficiency of insulin. You will probably have to give insulin injections to correct the deficiency. (Don’t worry. It’s easier than you think.)
   
2. The main symptoms of diabetes mellitus are excessive urination, excessive thirst, excessive appetite, and weight loss. Treatment should control these symptoms. Watching for these symptoms is the best way to know how your pet is doing.
   
3. The starting insulin dose is going to be based on averages and will be tweaked based on trial and error, depending on both test results and control of the symptoms.
   
4. You can save a lot of money if you get your own glucose meter and learn to do blood sampling at home (it’s easier than you think).
   
5. Using too little insulin is a problem in the long term, but too much insulin is potentially an emergency in the short term. Be sure you know how to recognize hypoglycemia and what to do about it. See Summary, below.

What is Diabetes Mellitus?

In order to understand the problems involved in diabetes mellitus it is necessary to understand something of the normal body’s sugar metabolism.

The cells of the body require fuel in the form of fat or sugar to conduct their daily activities.  Some tissues can use either sugar or fat depending on circumstances, and some tissues (such as the brain and nervous system) depend almost exclusively on sugar as fuel. Diabetes mellitus mostly involves the metabolism of sugar (in particular, a sugar known as glucose), so we will focus on the sugar part of the situation. Glucose comes from the diet in the form of starches and sugars that we eat.

Tissues cannot absorb glucose without a hormone known as insulin. Insulin is produced by the pancreas as part of the body’s natural blood sugar regulation. Insulin can be considered to be a key that unlocks the door, allowing sugar in the bloodstream to enter the body’s cells. Once inside the tissues, glucose can be burned for fuel or stored, but without insulin, the sugar stays in the bloodstream and cannot be used by the body.

Ketones in urine for three days or more in a row warrant a visit to the veterinarian. 

The body’s tissues are starving and the bloodstream has plenty of glucose to feed them, but without insulin, the glucose is unavailable.

So What Symptoms Result from this?

Because there is no way to remove glucose from the bloodstream, blood sugar levels are astronomically high. Normally, the kidney is able to conserve the bloodstream’s glucose but its mechanisms are overwhelmed and glucose spills into the urine in high amounts. If we continue our food delivery analogy, all the undeliverable food must be dumped. In the body, glucose dumping happens in the kidney with extra glucose dumping in the urine. This process involves the use of a lot of water with the ultimate result being a lot of urine being produced to process all that glucose to dump. This translates into excessive thirst and urination.

The tissues of the body are unable to access any of the glucose they need for fuel and are basically starving. Fat is mobilized and muscle is broken down to help feed the tissues but it does not do much good without insulin to bring fuel inside the cells. The patient shows excessive appetite because his body is in a state of starvation. Because the body is rapidly breaking itself down, weight loss is also a classic sign.

All the sugar in the urine provides a desirable growth medium for bacteria, and urinary tract infection is a common finding in diabetes mellitus. 

In diabetic dogs (but not cats), a specific type of cataract rapidly develops in the eye when high amounts of glucose enter the lens. Glucose normally feeds the lens, but the amounts of glucose coming into a lens in the diabetic state are much higher. Excess glucose is converted to another sugar called sorbitol, which in turn attracts water. The excess water disrupts the clarity of the lens, creating a diabetic cataract, which leads to blindness in almost all diabetic dogs. 

The main symptoms of diabetes mellitus are:

• Excessive Thirst
• Excessive Urination
• Excessive Appetite
• Weight Loss

Is it like Human Disease? Will We Need to Give Insulin Shots?

Dogs: Diabetes is most likely permanent and yes on the insulin shots.

Cats: Diabetes might not be permanent. Yes on the insulin shots if you want a chance at remission.

Diabetes mellitus is a classical disease in humans and most of us have heard some of the terms used to describe it. In humans, diabetes is broken down into two forms: Type I and Type II. These are also referred to as juvenile-onset and adult-onset diabetes or insulin-dependent and non-insulin-dependent diabetes. In short, Type I is the type where the pancreas produces no insulin at all, and Type II is the type where the pancreas produces some but not enough. Many pet owners wonder if dogs and cats have similar categories for their diseases.

Virtually all dogs have insulin-dependent diabetes and must be treated with insulin. There is no way around it. Their condition is similar to the Type I diabetic human in many ways.

Treatment: Giving Insulin by Injection

Since deficiency of insulin is the problem, it’s not surprising that giving insulin is the solution. You will need to learn to give injections, which is daunting to some owners at first, but almost everyone quickly becomes an expert. 

First, an insulin type and dose need to be selected. There are several types of insulins and it is not possible to know exactly how much insulin your individual pet will require; trial and error is needed. Your veterinarian will make a guess based on what works for other cats and dogs and what has been reported in the literature. Most pets require injections twice a day, approximately 12 hours apart, in conjunction with a meal. Because an overdose of insulin is potentially an emergency, it may be prudent to start with once-a-day insulin, just in case. If you like, discuss the pros and cons of each approach with your veterinarian. 

Insulin has traditionally been given by syringe in a shot, but insulin pens are proving more and more popular. The syringe method involves buying a box of syringes and a bottle of insulin, drawing up a measured amount of insulin, and giving a shot. The pen involves applying a needle tip to the pen, dialing a dose on the pen, sticking the tip into the pet’s skin, and pressing a button on the pen. Most people feel the pen method is much easier to perform but it may be difficult to find needle tips that are long enough for pet use as pet skin is much thicker than human skin.  In some situations, the pen is used as a dispenser for the syringe as the pen cartridges may be more cost-effective than bottles of insulin. Without video or first-hand experience with insulin pens or syringes, it may be hard to visualize the difference. See our section on insulin administration for more details. Not all pet insulins are available in a pen format. Your veterinarian will instruct you regarding options. 

Some insulins are available from the neighborhood pharmacy and some are available only through veterinary offices and veterinary pharmacies. Your veterinarian will either provide you with supplies or will give you the necessary prescriptions. If you are using syringes (instead of a pen) be sure the syringes and insulin concentration match. Insulin syringes are marked in insulin units (either U-100 syringes for 100 unit/cc insulins or U-40 syringes for 40 unit/cc insulins). Whenever you receive more supplies, always double-check these numbers.  

Never alter the insulin dose recommended by your doctor. To determine whether dose adjustments (or even a different type of insulin would be more appropriate), the pet will need a “glucose curve” where sugar levels are tracked over 10-24 hours. This can be done either by testing glucose levels with a glucose meter every 2 hours or so or by using a continuous monitor such as a FreeStyle Libre®. If a meter is used, it is best to test blood glucose in the pet’s own home and send the values to the vet but the curve can certainly be performed in the vet’s office. Note that stress and anxiety will alter blood glucose levels which means that values obtained at home will be more representative of the pet’s situation. 

Treatment: Oral Agents (Cats only)

Some cats will qualify for oral treatment of their diabetes. There are three medications that might be employed for this: bexagliflozin, velagliflozin, and glipizide.  

Bexagliflozin, an oral tablet medication, and velagliflozin, an oral solution (liquid), are options for some cats with diabetes mellitus where insulin injections are not practical.  Both of these drugs increase the kidneys’ ability to remove extra glucose from the bloodstream, keeping blood sugar levels in check. Lower blood sugar levels allow the pancreas to recover some and may alleviate many symptoms of diabetes. On the flip side, only certain cats will qualify for use, and there is potential for some very serious side effects. This includes diabetic ketoacidosis, a condition where insulin becomes so low that blood sugar cannot be used well in the body’s cells.  Following your veterinarian’s recommendations on proper monitoring is crucial. 

Finally, glipizide is a human medication used to reduce glucose levels by causing the pancreas’ beta cells to actually produce insulin.  In order for glipizide to have an effect, healthy beta cells need to be present. Glipizide is not as effective as bexagliflozin or velagliflozin in lowering blood glucose levels, so it does not include the intense monitoring or the same risk for complications as the others do. It is typically used for borderline patients or patients where insulin injections are simply not possible. Approximately 25% of cats will respond to this medication.

The various insulin formulations have different storage requirements. Check with your veterinarian for the proper storage of your pet’s prescribed insulin.

Diet and Feeding

Regulation can generally be worked out on whatever diet the pet is eating but there are some diets and feeding strategies that are helpful. For dogs, high-fiber/low-fat diets are preferred as they slow the absorption of sugars in the diet and help maintain a more regulated blood sugar level. Fiber also seems to make the body’s tissues more sensitive to insulin which also helps with regulation. Rewards are often employed to facilitate the insulin injection experience but these calories can add up and interfere with regulation so be sure your veterinarian is aware of all food items.  Diabetic dogs are best fed in two meals, approximately 12 hours apart. After they have been seen to eat their food, their insulin dose can be given.

For cats the strategy is different. First, cats seem to do best fed in multiple small meals daily so they should be allowed access to food at all times. Second, the high protein/low carbohydrate diets seem to be the most conducive to regulation. There are specific prescription diets, both canned and dry, for diabetic cats.

Learn more details on handling diets and feeding for cats and dogs.

What about Home Glucose Testing? 

Home glucose monitoring has many benefits: glucoses are monitored in the comfort of the pet’s own home without alterations from vet visit anxiety, a lot of money can be saved by monitoring at home, and questions about glucose status can be quickly answered and addressed. There are two ways to monitor glucoses at home: Continuous monitoring and a glucose meter.

Continuous Monitoring 

Continuous monitors have changed the way diabetic pets are monitored. A sensor with a tiny needle is implanted in the pet and paired wirelessly to either a phone or a reader. It reads tissue glucose levels constantly and reports its data to the device of your choice as well as to an internet portal where your veterinarian can access it. The sensor setup lasts up to 2 weeks and typically costs less than an in-house glucose curve run in the hospital. This is a fantastic option when it is time to get get a glucose curve. If one simply wants to spot-check a glucose level, one will need a glucometer and you will need to be able to take a blood sample from your pet.

Glucometer/Glucose Monitoring

 Many pet owners like to check glucose levels prior to insulin injections on a daily basis or simply want the ability to check a glucose level if there is a concern for hypoglycemia. For these situations, a glucometer is needed.  Human meters can be obtained at any drugstore, but we recommend getting a veterinary meter as the calibration is different. AlphaTrak is a popular brand, but there are presently several other brands available. 

The meter kit will contain measuring strips, solutions for calibration, and a spring-loaded lancet device for taking blood samples (usually from the ear margin). For details, please visit the Diabetes Monitoring section of this library. Taking single-drop blood samples turns out to be easier than you might think, and video links are provided in the monitoring section. Still, not every pet is amenable to blood sampling, and we do not want anyone getting bitten or scratched.

If you choose to use a glucometer at home, be sure to keep a log of when your pet was fed, when insulin was given, and what the glucose levels were that you found. (There are many phone apps to assist with this). Bring this log to your veterinarian when you come for checkups. Glucose levels obtained prior to the first insulin administration of the day are particularly useful. Your veterinarian will also be particularly interested in signs associated with poor regulation: excessive thirst, excessive urine production, excessive appetite, and weight loss

See the insulin administration guide for cats.

Hypoglycemia and Other Things to Watch for

The most serious problem to watch for is hypoglycemia (low blood sugar). This results from a mismatch in food consumption and insulin dose. If the dose is too high, you can get hypoglycemia. If the pet doesn’t eat, you can get hypoglycemia.  Your pet may look simply tired, weak, or sleepy. If she is roused, she will seem drunk or may not be able to fully come to alertness. This can be an emergency and can progress to seizures, so it is good to know what to do at home to prevent disaster.

If your pet appears wobbly or drunken, the blood sugar level may have dropped too low. This occurs after an insulin overdose. First, try to get your pet to eat. If the pet will not eat, administer light Karo syrup, honey, or even sugar water at a dose of one tablespoon per 5 pounds. If no improvement occurs, immediately see your veterinarian for emergency treatment. When your pet is more stable, a glucose curve will be needed to determine why this happened and what a more appropriate insulin dose might be.

It is best to make sure that your pet has recently eaten before giving the scheduled insulin dose.

Other Reasons to Return to the Vet

Bring your pet in for a re-check exam and testing if you note any of the following: 

• the pet seems to feel ill.
• the pet is losing weight.
• the pet has a ravenous appetite or loses its appetite.
• the pet seems to be drinking or urinating excessively. 
• the pet becomes disoriented or groggy.

It is important for diabetic pets to have their teeth cleaned annually. Dental tartar seeds the body with bacteria and when blood sugar levels run high, infections in important organs can take root. The kidneys and heart are particularly vulnerable.

Some Pets are Difficult to Regulate

Your pet will probably require re-regulation at some point. There may be an underlying reason to sort out. If your pet seems to fit into this category, some reasons could be:

• Improper administration of insulin. If possible, have your doctor observe you giving the insulin to your pet. Another possibility is that your insulin may be out of date.
   
• Rapid insulin metabolism. Insulin wears off quickly in some animals. Your pet may require a different type of insulin or a second injection during the day, or even additional injections during the day.
   
• Insulin overdose may actually lead to elevated glucose levels (and clinical signs of diabetes mellitus). In this situation, too much insulin brings the blood glucose too low, and other hormones respond to bring it back up (and generally overdo it).  
  
• Steroid administration (such as prednisone, prednisolone, etc.) will interfere with insulin. 
    
• Progesterone, a female hormone, also interferes with insulin. Unspayed female diabetics should be spayed once they are sufficiently regulated.

For more details on trouble with regulation, read about hard-to-regulate cats.

Additional Information on Feeding a Diabetic Pet

Regulation is achieved via a balance of diet, exercise, and insulin. Realizing that therapeutic diets are not always attractive to pets, there are some ideal foods that should at least be offered.

The most up-to-date choice for cats is a low-carbohydrate, high-protein diet. These diets promote weight loss in obese diabetics and are available in both canned and dry formulations. For dogs, high-fiber diets are still in favor as fiber seems to help sensitize the pet to insulin. Talk to your veterinarian to select an appropriate choice for your pet.

Avoid soft-moist diets as sugars are used as preservatives. Avoid bread and sweet treats. If it is not possible to change the pet’s diet, then regulation will just have to be worked out around whatever the pet will eat.

In Summary:

1. Diabetes is caused by a deficiency of insulin. Diabetes mostly involves metabolizing sugar, particularly a sugar called glucose. You will probably have to give insulin injections to correct the deficiency. It’s easier than you think.
2. A body requires fuel in the form of fat or sugar. Glucose comes from a diet of starches and sugars. Tissues cannot absorb glucose without insulin, so the level of insulin affects the glucose level.
3. The main symptoms are excessive urination, thirst, appetite, and weight loss. Watching for these symptoms is the best way to know how your pet is doing.
4. Tissues are unable to access any of the glucose they need for fuel and are basically starving. Rather than going into tissues, unmetabolized glucose goes into the bloodstream but cannot be removed from there, so glucose levels become astronomically high. The kidney compensates by dumping glucose straight into the urine. The kidney needs much water to do that, so a larger volume of urine is made just for dumping, causing a cycle of excessive thirst and urination.
5. Your veterinarian will select the first dose of insulin based on glucose averages and will tweak it thereafter. You can use either a syringe or an insulin pen.
6. While using too little insulin (high blood sugar or hyperglycemia) can lead to problems, using too much insulin (low blood sugar or hypoglycemia) is potentially life-threatening in the short term. Low blood sugar creates listlessness and potential unconsciousness; the fix is to offer food immediately.
   • Extremely low blood sugar can cause tremors, seizures, weakness, collapse, and incoordination, in addition to other signs.
   • Extremely high blood sugar can cause seizures, circling, pacing, weakness, coma, and incoordination, among others.
   • Both are emergency situations, and you should see your veterinarian or an emergency hospital immediately.
7. Never alter the insulin dose without discussing it first with your veterinarian.
8. It’s easiest for your pet if you get a glucose meter, install a continuous monitor, and do blood sampling at home. That way, you can find out their glucose status right away and do something about it.
9. Some pets are difficult to regulate. Yours will probably require re-regulation at some point. Regulation needs a consistent balance of diet, exercise, and insulin.
10. The current choice of food for diabetic cats is a low-carbohydrate, high-protein diet. High-fiber diets are best for dogs. 
11. Dogs: Diabetes is most likely permanent, and they need insulin shots.
12. Cats: Diabetes might not be permanent. To have a chance of remission, they need insulin shots. Some cats might be able to take pills rather than shots.

It is extremely important to seek your veterinarian’s help as quickly as possible if you suspect a wound has become infected. If left untreated, cellulitis can quickly become very serious, sometimes resulting in the tissues becoming necrotic (tissue death), and can be fatal to your pet in severe cases.

Symptoms

Cellulitis can occur on any part of your dog’s or cat’s body where there is a break in the skin, allowing bacteria to enter. For this reason, cellulitis is often the secondary health issue, the first being the wound that breaks the skin. A wound does not always need to be large for bacteria to enter and may go unnoticed until the symptoms of cellulitis appear.

In the affected area, your pet may have:

• sensitivity and pain;
• skin that feels hot to the touch, redness;
• an abscess;
• accumulated pus or green discharge;
• swelling;
• obsessive licking of the area.

The infection may cause your pet to have a fever, refuse to eat, act lethargic, or appear depressed. You may notice an unpleasant odor if there is an abscess or discharge. Often, this odor is the first clue that something is going on with your pet if you are unaware that they have been injured.

Treatment

Your veterinarian will take your pet’s history and examine them for wounds or abscesses. Blood tests and cultures may be needed to determine the type of bacteria in your pet’s body and their overall health.

If an abscess is found and hasn’t already burst, it will be opened, drained, and cleaned, usually under anesthesia or sedation. A piece of sterile tubing, cloth, or other material is often placed into the abscess to allow continued drainage. Stitches may be used to keep this drain in place, and drains are often covered with a bandage.

A lab test may be performed on the fluid from the abscess to identify further the culprit or culprits causing the infection. This is important to ensure that the correct antibiotics are prescribed. Culture results can take several days to return, and a change in antibiotics may be needed. Your pet may have other issues stemming from the original injury, which will be treated as needed.

Your veterinarian will send you home with antibiotics to tackle the infection, possibly anti-inflammatories, and pain medication as needed. Based on culture results, antibiotic therapy can be tailored to your pet’s specific needs, and multiple antibiotics are sometimes needed. Additionally, topical antibiotic ointments are available. You will likely be given a list of aftercare instructions, which may suggest the continued use of warm compresses on the abscess site to encourage drainage. Use a protective e-collar if your pet won’t leave the treated area alone. These cones are available at your veterinary clinic or a pet or feed store.

Be sure to finish the prescription medications as directed.

Sometimes, the drain is not enough, and the abscess fills up again despite your best efforts. Contact your veterinarian if this happens.

Should You Be Concerned About Catching This from Your Pet?

Always wash your hands well before and after treating your pet, and wear gloves if possible. If your immune system is compromised, let your veterinarian know, and pay special attention to hygiene when dealing with your pet’s wound.

Prognosis

Your veterinarian is your best source for information and treatment and for receiving a positive outcome when dealing with cellulitis.   

In minor cases and with proper and timely care, your pet should recover without problems.
