FRYour dog's pancreas has become inflamed, often with no clear cause. Here is when to go, what to avoid at home, and how to limit relapses, holidays included.
Some signs cannot wait
A swollen, hard or very painful belly, retching with nothing coming up, nonstop or bloody vomiting, a very flat dog, laboured breathing, jaundice: go now. One is enough.
See the full listWhat is happening, and where it comes from
The pancreas, a small gland against the stomach and the start of the intestine, makes digestive juices and insulin. In pancreatitis, those juices switch on too early and damage the gland. An acute attack can heal without a trace; a chronic form, often quiet, leaves lasting damage and can come back. Both can be serious.
Where it comes from
Most of the time, no precise cause is found. An unusual fatty meal, leftovers or the garbage are classic triggers. Some breeds are predisposed, the Miniature Schnauzer in particular. Excess weight, very high blood fats, some hormonal diseases and some medications count too.
The signs, and when to go
He refuses food, he vomits, he is flat, his belly hurts, sometimes there is diarrhea. A dog in pain does not always cry out: he may take the prayer position (front end down, back end up), stretch again and again, or keep to himself. A mild form sometimes looks like nothing more than a poor appetite.
Go now: any one of these is enough
- His belly is swollen, hard or very painful; he cannot find a position, or stays in the prayer position.
- He tries to vomit and nothing comes up, or only foam, especially if his belly is swelling (gastric torsion).
- He is vomiting nonstop: nothing stays down, not even water.
- He is vomiting blood (red, or like coffee grounds), or his stools are black and tarry.
- He is very flat: he cannot stay standing, he barely responds, or his gums are pale or grey.
- He is breathing fast at rest, or with effort.
- Yellow is showing on his gums or the whites of his eyes.
- He is staggering, collapsing or having a seizure.
- He may have swallowed an object or something toxic: do not make him vomit.
- He is diabetic, on insulin, and eating less: call us before the injection, or a 24/7 centre if we are closed, without deciding the dose on your own. If he is weak, disoriented, vomiting, breathing fast, or his breath smells oddly sweet, go.
Call us on the way. Outside our opening hours we do not run an emergency service: go to a veterinary centre open 24/7, then tell us so we can take it from there.
The same day
A dog who refuses food completely is seen the same day. If he has had pancreatitis before, he has no margin: call at the first real meal refused. If we are closed, a 24/7 emergency centre answers.
Until the exam: nothing forced, no home medications
A dog whose pancreas may be inflamed must have nothing forced into his mouth until he has been examined: forcing him makes him vomit and makes him worse. What he takes on his own, let him have; what you put into his mouth, never. Do not fast him on your own initiative, and do not make him vomit.
Ibuprofen (Advil), naproxen (Aleve), aspirin
stomach ulcers, digestive bleeding, kidney damage. Never a human anti-inflammatory, for any reason. Cats are even more sensitive.
A prescribed anti-inflammatory
if he is on one, hold the next dose and call us, or a 24/7 centre if we are closed.
Acetaminophen (Tylenol)
toxic to a dog's liver and blood, with no safe home dose. In cats it is fatal, even a single tablet.
Pepto-Bismol, Gravol, Imodium, antacids, leftover prescriptions, another animal's medication
never without direction. They mask the signs, and Pepto-Bismol, a cousin of aspirin, turns stools black.
If you have already given something
Tell us right away: call us, or a veterinary centre open 24/7 outside our hours. It is not a reproach.
The exam: no single test is enough
Basic bloodwork, run here, does not prove pancreatitis: it measures how serious it is and rules out other causes. A pancreas-specific test (lipase) supports the diagnosis: high, it backs it up when the rest fits; normal, it makes it less likely without ruling it out. Depending on the test, the sample is run here or sent to an outside laboratory: ask which applies and how long to expect.
An X-ray mainly rules out something else, such as a swallowed object. The full organ by organ ultrasound, the one that looks at the pancreas, is a separate, planned appointment; it takes place here, with our own team or with a specialized imaging team that travels to us. A normal result does not rule out pancreatitis.
Treatment: supporting the body
No medication switches pancreatitis off: we support the body while it settles. He gets IV fluids, we treat his pain even when it does not show, and his nausea, then we offer food early, a little at a time. After the exam, we present a treatment plan.
Hospitalization, here
Hospitalization here is day hospitalization: your dog is admitted, treated and rechecked on site during our opening hours, and a stay can run over several days, with a recheck each day. We do not provide continuous medical monitoring overnight. When a dog needs to be watched without a break, we stabilize first, then we arrange the transfer to a 24/7 centre, with the full record. In every case, we tell you at admission what the plan is for the night.
After the episode, and over the holidays
What to watch
From now on, tell us if he drinks and urinates a lot (diabetes), or if he loses weight while eating well, with large, pale stools (a shortage of digestive enzymes).
The holidays: more temptations
Gravy, poultry skin, roast fat, cheese, tourtière, cretons: the holiday table is full of them. Keep him on his usual food, warn your guests, leave nothing within his reach and take the party garbage out. If he has had pancreatitis before: nothing from the table, not even plain food, without our okay.
