Acute Pancreatitis in Dogs

Acute Pancreatitis in Dogs

The pancreas has many functions, including the production and secretion of digestive enzymes and the production of insulin. Digestive enzymes are critical for food digestion, while insulin aids in the control of the metabolism and blood-sugar levels. Pancreatitis means “inflammation” of the pancreas and acute means “sudden.” When the pancreas becomes inflamed, digestive enzymes that are normally inactive until they reach the small intestine become active in the pancreas instead—resulting in pain and swelling as the pancreas actually begins to digest itself.

Risks of Acute Pancreatitis in Dogs

There are many suggested causes of acute pancreatitis including: obesity, high-fat diets, endocrine diseases such as hypothyroidism, and various medications or toxins. Even if your dog doesn’t normally eat a high-fat diet, the introduction of a large amount of fatty food all at once can cause acute pancreatitis. Veterinarians see an increase in pancreatitis around the holidays, since many people think a nice way to celebrate is to share their holiday meals with their dog. In addition, dogs that get into garbage are much more likely to develop pancreatitis, so be sure to keep your trash out of your dog’s reach! Pancreatitis can occur in any dog, but some breeds are more susceptible to this disease. They include the miniature schnauzer, miniature poodle, and cocker spaniel. Additionally, pancreatitis is more common in middle-age to older dogs, overweight dogs, and females.

Symptoms of Acute Pancreatitis in Dogs

The most common symptoms of acute pancreatitis in dogs are loss of appetite, vomiting, and abdominal pain. Other symptoms you may notice include:

• Swollen abdomen

• Abnormal posture; arching of the back

• Diarrhea

• Lethargy

• Restlessness

• Gagging

• Diagnosis/Treatment

Your veterinarian will take a complete history and perform a thorough physical exam. Additionally, diagnostic tests will be required to identify if your dog has acute pancreatitis. These may include:

• Chemistry tests to evaluate kidney, liver, and pancreatic disease or dysfunction, as well as blood sugar levels

• A complete blood count to screen your pet for infection, inflammation, or anemia and other blood-related conditions

• Electrolyte tests to ensure your dog is neither dehydrated nor suffering from an electrolyte imbalance

• Pancreas-specific tests to help diagnose or rule out the disease

• Imagaing studies to evalutate the pancreas and other abdominal organs

The treatment of pancreatitis depends on the severity of the disease and may include:

• Hospitalization at the veterinary clinic and in more severe cases 24 hour intensive care and monitoring

• Intravenous fluids

• Pain medicine

• Antivomiting medication (antiemetics)

• Antibiotics, if a secondary bacterial infection is suspected

• Nutritional support

• Other medications, depending on your dog’s symptoms

Keep in mind that your veterinarian may recommend that some diagnostic tests, such as the CBC, chemistry tests, and pancreatic-specific tests be repeated to monitor your dog’s progress during treatment.

Your veterinarian will recommend a treatment plan that is specific for your pet. Make sure you give all medications as directed and carefully follow any dietary recommendations. Following recovery a low fat diet may be recommended to decrease the chance of recurrence. Keep a close eye on your best friend; if he or she becomes lethargic or stops eating, call your veterinarian right away.

Prevention of Acute Pancreatitis in Dogs

While you can’t completely prevent acute pancreatitis, the following will help reduce the risk of your dog developing the disease and ensure his health and well-being:

• Don’t let your dog become overweight—weight management is just as important for our four-legged friends as it is for us!

• Avoid high-fat diets.

• Avoid giving your dog table scraps, especially if he isn’t accustomed to eating people food.

• Make sure you discuss all medications your dog is receiving with your veterinarian.

• Don’t let your dog have access to garbage

If you suspect your pet is overweight or potentially suffering from pancreatitis, please call your vet.

Idiopathic Epilepsy in Dogs

Epilepsy is a general term for neurological disorders that are characterized by recurrent seizures. In some cases, the seizures are caused by trauma, a toxin, a brain tumor, an infection, or an issue with your dog’s blood, kidneys, or other organs. At other times, the epilepsy is referred to as “idiopathic,” which simply means that there is no identifiable, underlying cause.

Seizures commonly fall into two categories: generalized (grand mal) or partial (focal). Generalized seizures commonly appear as involuntary jerking or twitching movements of all four limbs with loss of consciousness. Partial seizures may involve one limb, side of the body, or face. Partial seizures may progress to generalized seizures. Seizures may also result in abnormal behavior, vocalization, salivation, chomping/chewing, and involuntary urination and defecation.

Dogs with idiopathic epilepsy typically have their first seizures between the ages of 6 months to 6 years. Though idiopathic epilepsy can occur in any breed, it is considered an inheritable disease in many breeds and in some breeds a genetic basis has been identified. Therefore, dogs diagnosed with idiopathic epilepsy should not be used for breeding. Commonly affected breeds include:

• Labrador retrievers

• Golden retrievers

• Poodles

• Keeshonds

• Beagles

• German shepherds

• Dachshunds

• Irish setters

• Cocker spaniels

Symptoms of Epilepsy in Dogs

Prolonged seizures lasting more than 5 minutes or two or more consecutive seizures without full recovery are referred to as status epilepticus. This is a true emergency and you should seek immediate veterinary care for you pet. Two or more seizures in 24 hours are referred to as cluster seizures and are an indication for beginning anti-seizure medication.

In dogs, seizures often occur in three distinct phases:

1. The first is called the aural phase and the most common signs are behavioral changes. These changes may be subtle and include restlessness, attention seeking or anxious behavior.

2. The second phase, called the ictal phase, is when the seizure itself takes place. A seizure can last from just a few seconds to several minutes.

3. The final phase is called the postictal phase, which occurs after the seizure. During this phase, your dog may seem restless, incoordinated and/or disoriented. Occasionally, temporary blindness, deafness or other neurologic abnormalities may occur.

It may be difficult to watch your pet have a seizure but most are of short duration and cause no permanent harm. Avoid being bitten by keeping your hands away from your pet’s mouth during a seizure. If it can be done safely, provide padding and move your pet away from stairs to prevent injury.

Diagnosis of Epilepsy in Dogs

Your veterinarian will take a complete history and perform a thorough physical and neurological exam to determine if there is an identifiable, underlying cause of your dog’s seizure.

In order to do so, the following tests may be recommended:

• Chemistry tests to evaluate kidney, liver, and pancreatic function, as well as sugar levels and electrolytes

• A complete blood count to screen for infection, inflammation, anemia, and other blood-related conditions

• Urinalysis

• PCR testing and/or serology to evaluate for infectious diseases that may cause seizures

• Referral to a neurologist for advanced testing including MRI and cerebrospinal fluid analysis

• Cultures, PCR testing, and other specialized tests that can identify if specific parasites or diseases could be the cause

Treatment of Epilepsy in Dogs

Epilepsy cannot be cured, but it can usually be controlled with anticonvulsant drugs. If your veterinarian determines that your dog’s epilepsy is idiopathic, one or more of the following medications may be prescribed:

• Phenobarbital helps reduce the frequency of your dog’s seizures and is the most prescribed medication for dogs with idiopathic epilepsy. It is generally a well-tolerated drug.

• Potassium bromide is another seizure medication that may be added to your dog’s treatment, if she does not respond well to phenobarbital alone.

With these medications, as with all drugs, some patients experience side effects. In order to make sure an adequate dose is being given, and to monitor for side effects, it is important that blood levels of each medication as well as complete blood counts and blood chemistry profiles be monitored periodically. Liver function tests may also be indicated. Your veterinarian will advise what monitoring needs to be done and how often. Medication dosages should not be changed without talking to your veterinarian.

Dogs diagnosed with idiopathic epilepsy may require treatment for life, and sometimes more than one drug is needed for adequate seizure control. And while many dogs are well controlled, some are not despite multiple medications. In addition, adequate seizure control does not necessarily guarantee that a dog will be entirely seizure free. The degree of seizure control may need to be balanced against potential side effects of the medications.

Management of Epilepsy in Dogs

Besides medication, there are many ways for you, yourself, to help manage your pet’s epilepsy:

• Maintain a seizure log that lists date, time, length and severity of seizures as well as videotape and share this with your veterinarian

• Do not change or discontinue medications without consulting your veterinarian

• Have blood work and other lab work done when recommended by your veterinarian

• Consult your veterinarian whenever you notice a change in your pet’s condition

• Put a medical alert tag on your pet’s collar so that if he becomes lost, whoever finds him will be aware of their seizure disorder and need for medication.

Several treatments are available for pets with epilepsy. By working closely with your veterinarian, you can maximize the chances of controlling the disorder and giving your pet a long, happy, and comfortable life.

Diets for Pets with Heart Disease

It is now known that the diet is a very important part of medical therapy for heart disease and one in which owners have the most crucial role. New research is showing that proper nutrition may be able to slow the progression of heart disease, minimize the number of medications required, improve the quality of life or, in rare cases, actually cure the disease.

Maintaining Optimal Weight

A key goal for the nutritional management of heart disease is to maintain optimal body weight, because both weight loss and obesity can be harmful to your pet. Owners should watch their pets for loss of overall body weight and loss of muscle (cachexia describes muscle loss seen in animals with heart disease).

Many pets with heart failure will not eat as much, as frequently, or the same things as when they were healthy—this is called anorexia. This can be an important factor in the weight and muscle loss that occurs. Maintaining your pet's interest in food is a tricky, yet important, task but there are several tips to achieving this.

First, try giving more frequent, but smaller meals. Cats frequently are more interested when the food is warmed. Dogs are less predictable, but will usually prefer one temperature over another (try different temperatures—warmed, room temperature, cold or even near-frozen).

Another method to manage reduced or changed appetite in an animal with heart disease is to gradually replace their current food with a new one. For example, switch from a dry food to a canned food or change to a different brand. However, be sure to talk to your veterinarian about the diet that is most appropriate for your pet.

Finally, flavor enhancers such as cooked meat or fish (without any salt; avoid deli meats) for dogs and cats, or sweeteners (such as yogurt, maple syrup, applesauce or honey) for dogs may be added to the diet to promote eating. Fish oil may be given to help with cachexia.

As it is important to make sure animals are not too skinny, it is also necessary to make sure they are not too heavy. Owners often find that severely overweight dogs and cats with heart disease that successfully lose weight, appear to have less trouble breathing and are more comfortable. A special diet may be prescribed for your dog or cat to help treat the heart disease as well as to maintain their optimal body weight.

Important Nutrients for Pets

Nutritional deficiencies are now uncommon in dogs and cats unless owners are feeding a nutritionally unbalanced diet. If your animal is eating a homemade, raw or vegetarian diet, or a diet made by a small company, please let your veterinarian know this as it could be important in the diagnosis or treatment of your pet.

Even if your pet doesn't have a specific nutritional deficiency, increasing the levels of certain nutrients may have benefits in the treatment of heart disease. Nutrients that may need to be supplemented are described below. It is important to keep in mind that dietary supplements have little regulation so quality control can be a big problem. Cummings School recommends using dietary supplements that bear the logo of the United States Pharmacopeia Dietary Supplement Verification Program (DSVP), which tests human dietary supplements for ingredients, concentrations, dissolvability and contaminants. Another good resource is ConsumerLab.com, which performs independent testing of dietary supplements primarily for human supplements but also for pet products as well.

Taurine

Taurine is an amino acid which, if deficient, can cause a specific heart disease called Dilated Cardiomyopathy (DCM) in cats. Complete and balanced commercial cat foods have enough taurine but diets that are not complete and balanced (labeled as for intermittent or supplemental use only), vegetarian diets or homemade diets can be too low in this nutrient. If your cat is diagnosed with DCM, the cardiologists will usually test their blood taurine level to see if they are deficient and prescribe supplements to help treat the disease.

Dogs, unlike cats, are not thought to require taurine in the diet. However, certain breeds (Cocker spaniels, Newfoundlands, St. Bernards, English setters, Labrador and Golden retrievers) may require some in the diet to avoid a deficiency. Lamb and rice diets, very low protein, and high fiber diets in these predisposed breeds may make it more likely for them to develop taurine deficiency. Dogs of these predisposed breeds that develop DCM may have their blood tested for taurine levels. Most dogs with DCM do not have taurine deficiency but when levels are low then taurine supplementation can help in the management of heart failure.

Omega-3 Fatty Acids (Fish Oil)

Certain types of fatty acids present in fish oil (called omega-3 fatty acids) have been shown have a positive effect in dogs with heart disease. Omega-3 fatty acids do not help to prevent heart disease as they do in people. This is because in people, omega-3 fatty acids have a beneficial effect in coronary artery disease, which does not occur in dogs and cats. In pets with heart disease, fish oil is recommended for dogs and cats who have reduced or altered appetite or any muscle loss (cachexia). Omega-3 supplements can also be used (in addition to appropriate medication) in the treatment of dogs with abnormal heart rhythms (arrhythmias).

Fish oil may be purchased over-the-counter at almost all human pharmacies but dose and quality of the products vary widely. Cummings School generally recommends a one gram fish oil capsule that contains 180mg of eicosapentaenoic acid (EPA) and 120mg of docosahexaenoic acid (DHA). The quality control of the individual product should be checked to ensure your pet is getting the right amount and is not getting unwanted nutrients or contaminants. Various ways to check quality control of dietary supplements are mentioned above.

With capsules of this size most dogs and cats can be given one capsule per 10 pounds of body weight. Fish oil is relatively safe but if your pet has a bleeding disorder or is already eating a diet high in omega-3 fatty acids, supplementation should be carefully considered with your veterinarian. Fish oil supplements should contain vitamin E as an antioxidant, but other nutrients should not be included. Cod liver oil and flax seed oil should not be used as sources of omega-3 fatty acids in dogs and cats.

Restricted Nutrients for Pets

While supplementing important nutrients may prove beneficial, it is equally true that reducing the levels of certain nutrients may have benefits in the treatment of heart disease. Nutrients that may need to be restricted are described below.

Sodium

Depending on the severity of heart disease, decreasing the amount of sodium in the diet can be beneficial. In pets with mild heart disease (those that are not showing any symptoms), only mild sodium restriction is recommended. If the heart disease is more advanced, causing a condition known as Congestive Heart Failure (CHF), greater sodium restriction is advised. Talk to your veterinarian about the diet that would be most appropriate for your dog or cat. Diets that are low in protein should be avoided unless the pet has severe kidney disease. Cummings School provides a reduced sodium diet list in the PDF format for your convenience.

While it is important to feed the most appropriate pet food given your animal's type, level of heart disease and other medical issues, it is also necessary to remember that large amounts of sodium can also come from treats, table food and the foods you might use to give daily medications. A list of treats for dogs with heart disease is also provided in the PDF format. Be sure to talk to your veterinarian about which treats can be safely fed to your pet.
