Clinical signs of pancreatitis in dogs

Dogs suspected of having pancreatitis may experience vomiting, lethargy and a painful abdomen, but clinical signs can be more vague. Pancreatitis can be mild or severe. Mildly affected dogs may experience dehydration, slight inactivity or an abnormal hunched posture (due to abdominal pain). Another classic sign of pain in the area of the pancreas is dogs adopting the play bow position for no reason. On the opposite end of the spectrum, severely affected dogs may have the following clinical signs:

• Elevated heart rate
• Decreased body temperature
• An enlarged, fluid-filled belly
• Yellowing of the eyes, skin and gums
• An abdominal mass
• Episodes of collapsing

Any dog can develop pancreatitis, and middle-aged to older dogs are at increased risk of developing the condition. Overweight dogs are also predisposed, along with dogs who are diagnosed with hypothyroidism, diabetes mellitus, Cushing's disease and hyperlipidemia, according to the Veterinary Information Network. Certain breeds, such as German Shepherds, are also more prone to developing chronic pancreatitis. This breed is also prone to another pancreatic issue called exocrine pancreatic insufficiency (EPI). This is where the pancreas doesn’t make enough digestive enzymes so the animals can’t digest food effectively. This means they tend to be thin and in poor condition, even though they eat ravenously. While EPI may arise on its own, it can also be caused by chronic pancreatitis due to damage to the cells, so the two often go hand in hand.

Miniature Schnauzers, Cocker spaniels, Yorkshire Terriers, Silky Terriers and Miniature Poodles may be at increased risk of acute pancreatitis. Both males and females may be affected. While any dog can develop pancreatitis, the best way to prevent a dog from developing this serious condition is to avoid feeding them fatty table scraps and treats.

Diagnosing pancreatitis in dogs

Reaching a diagnosis of pancreatitis can be quite complicated as the clinical signs are so vague. Your vet may recommend several types of blood tests and imaging, including:

• A full, general panel of blood tests to look for other diseases with similar signs
• A blood test to look for canine Pancreatic Lipase Immunoreactivity, or cPLI. This is an enzyme that is only produced in the pancreas. The inflammation of pancreatitis causes this enzyme to leak into the blood so it is usually a reliable diagnostic test.
• An abdominal ultrasound to look for an enlarged, swollen pancreas. If your vet does not have an ultrasound, they may refer your dog to a veterinary specialist for this examination. A few vets, usually at specialist centres, will perform a biopsy of the pancreas to get a definitive diagnosis. However, because biopsies are rarely undertaken in practice, the diagnosis of pancreatitis is often a presumptive one.

Treatment for pancreatitis in dogs

Dogs with acute pancreatitis usually require hospitalisation for fluid therapy, medications for pain and vomiting, and other supportive care. It's also essential to get these dogs eating as soon as possible once their condition is stable as this has been proven to speed up recovery. Because these dogs usually don't feel well and understandably may not have much of an appetite, your vet may recommend placement of a temporary feeding tube to ensure their caloric needs are being met until they've had more time to recover. While most dogs successfully recover from episodes of acute pancreatitis, this disease can be life-threatening and pets can deteriorate rapidly despite prompt, appropriate treatment. Pain medications are an important part of treatment because the condition is very painful... If your vet suspects pancreatitis, they may recommend transitioning your dog to a highly digestible, low-fat food to help prevent recurrent episodes or flare-ups.

Long-term outlook

The prognosis for dogs with pancreatitis is a challenge to predict. Most dogs will regain their health and pull through this disease, unless they are extremely ill when they arrive at the veterinary hospital. Even if your dog does require a lengthy hospital stay, this is not necessarily an indicator that they won't recover from this disease. The best outcomes are associated with prompt veterinary intervention, so if you catch clinical signs of pancreatitis in dogs, do not wait and see if they resolve on their own.

The prognosis for dogs with milder acute or chronic pancreatitis is generally better, particularly if a few lifestyle changes are made. Switching to foods low in protein and fat (since both are potent stimulators of pancreatic secretion), along with the addition of antioxidants and a program to support a healthy weight may all be recommended by your vet. However, it's important to understand that flare-ups may occur from time to time, even with a good response to your veterinarian's treatment plan. With a little patience and teamwork with your vet, as well as being able to recognise the early warning signs of a problem, you can give your dog a great chance at a relatively normal, healthy life.
