Chow Chow Pancreatitis and Diabetes: When One Organ Fails Twice

A single acute episode of pancreatitis, treated and recovered from, usually leaves the endocrine cells intact. The problem is repetition. Each episode replaces functioning tissue with scar, and scar produces neither enzymes nor hormones. Some dogs also carry a low-grade, smouldering inflammation that never produces a dramatic attack but grinds away at the organ across years, which is why a dog can become diabetic without an owner ever having witnessed an obvious crisis.

The reverse direction also exists. A diabetic dog with poorly controlled blood glucose has altered fat metabolism, and elevated circulating fats are themselves associated with pancreatic inflammation. So the two conditions can push each other along, and a diabetic Chow who suddenly stops eating and starts vomiting has to be assessed for pancreatitis rather than assumed to be having an insulin problem.

A third consequence sits alongside both. If enough enzyme-producing tissue is lost, the dog cannot digest food properly, a condition called exocrine pancreatic insufficiency. The signs are voluminous, pale, greasy stools and weight loss despite a good appetite, and it is treated with enzyme supplementation. A senior Chow losing weight while eating well deserves that test as well as a glucose check.

The routine is unglamorous and it is the treatment. Households that keep the schedule rigid do markedly better than those that keep it approximately.

If you think your Chow has pancreatitis & diabetes, the plan is three steps: write down what you have seen and when it started, book a veterinary appointment rather than waiting for the next flare, and take video of the behaviour or symptom before you go — the thing you are worried about rarely happens in the consulting room. Screening in the parents covers hip dysplasia, elbow dysplasia, entropion.

What the vet visit should produce is a diagnosis and a written plan, not just reassurance: what is being ruled out, what the monitoring interval is, and which signs mean you come back sooner. Ask what the treatment costs across a year rather than per visit, because that is the number that decides whether you are managing this condition or reacting to it.

Between appointments, keep a short log — dates, what you saw, what changed. It is the single most useful thing an owner brings to a follow-up, and for pancreatitis & diabetes it is often what separates a clear pattern from a guess.
