Thanksgiving Monday falls on the twelfth of October in 2026. Rather than a list of forbidden foods, this is a plan built around when things actually go wrong in a Calgary household: while the food is being prepared, while everyone is eating, during the clear-up, and on the Tuesday when the leftovers come back out.
Stage one: the kitchen, hours before anyone eats
The busiest cooking morning of the year is when a dog learns that counters are worth checking.
Raw dough proving in a warm kitchen is the one to keep well out of reach. Swallowed dough keeps rising in a warm stomach and ferments as it does, producing alcohol at the same time, so it causes two problems at once.
The bird is the other. A thawing or resting turkey left on a counter is reachable by a determined dog and by most cats. Along with the meat comes string, netting, a plastic pop-up timer and the absorbent pad from the packaging, all of which carry the smell that makes them worth swallowing.
Trimmings in an open kitchen bin are the third. Fat, skin and raw offcuts all end up there while people are busy.
What helps: put the dog somewhere else with something to chew while you cook, keep the bin behind a door from the moment prep starts, and never leave the bird unattended on the counter, not even to answer the door.
Stage two: the meal, and the guest who means well
The single most common source of a holiday problem is not the cook. It is a visitor who does not live with animals, holding a plate at dog height.
Fatty offcuts, skin and gravy matter most. A sudden load of rich food can inflame the pancreas, which is painful, occasionally severe, and shows up a day or two later as repeated vomiting, a tender belly, a hunched posture and a dog who cannot settle. Small breeds and dogs already carrying weight are more prone, though it happens to any dog.
Cooked bones are the other headline. They splinter, and we see broken teeth, cuts in the mouth, bones jammed across the roof of the mouth and blockages further down. Dogs who crack a tooth on a bone often hide the pain, so a check with our dental services team afterward is sensible.
Then there are the quieter ones. Onion, garlic, leeks and chives run through stuffing, gravy and most casseroles and damage red blood cells, with signs often delayed several days. Grapes, raisins and currants hide in salads, stuffing and baking and can injure the kidneys, with no amount considered reliably safe. Anything labelled sugar-free may contain xylitol, which drops a dog’s blood sugar fast and can harm the liver.
What helps: tell guests at the door, once, that nothing goes to the dog. Feed your pet their own meal at the same time you sit down, and give them a stuffed chew to work on. For most healthy pets, a few bites of plain turkey meat, stripped of skin and off the bone, are fine, and so is a spoonful of plain cooked pumpkin.
Stage three: the clear-up
The carcass goes in the bin, the plates get stacked, and everyone sits down. That twenty minutes is when a lot of dogs help themselves.
What helps: the carcass and the trimmings go straight outside to a secured bin or into the freezer until collection day, not into the kitchen bin. Wipe down counters, and check the floor under the table before the dog does.
Stage four: Tuesday
Leftovers come out, portions are generous, and a pet who was carefully managed all weekend gets a plate of scraps because the holiday is over. Pancreatitis from the holiday meal often arrives a day or two afterward, so Tuesday is squarely inside the window rather than outside it.
Two things specific to a Calgary long weekend
The door. Arrivals and departures are when pets slip out, and a mid-October evening here can be well below freezing. Make sure the microchip is registered to a phone number you currently use, put a tag on, and give a nervous pet a quiet room with the door shut rather than trusting the front hall.
Who is open. Clinic hours change over a long weekend. Save the number of an emergency hospital in your phone before Friday, alongside ours, so nobody is searching for it on the Monday.
When to phone rather than wait
Phone the same day if your pet vomits more than once, guards a sore belly, stands hunched, heaves without producing anything, seems weak, has pale gums, is breathing badly, or collapses. Phone as well for anything swallowed off the list above, even in a small amount, and even if your pet looks well. Our urgent care team would far rather hear from you early.
Cats deserve a separate mention. Counters interest them more than bins do, their tolerance for the allium family is lower again, and swallowed roasting string is an emergency in its own right. A cat who withdraws, hides or turns away from food once the guests have gone needs an appointment, since a couple of days without eating creates a problem of its own.
The pancreas is the organ most often involved in all of this, and our guide to pancreatitis in dogs and cats explains what it looks like and why rich food triggers it. If your pet is already overweight or on a specific diet, our nutrition counselling service can set up something workable before the holiday rather than after it.
Frequently asked questions
What can my dog safely have from the table?
Turkey meat on its own, unseasoned, skinless and boneless, in a small portion. Cooked pumpkin without spices, green beans, or carrot sticks also work. Think a few bites, not a plateful, and skip the whole idea for a pet with a delicate stomach or an ongoing condition.
My dog got into the bin overnight. What should I watch for?
Phone us in the morning rather than waiting for signs, especially if bones or a lot of fat were in there. At home, watch for repeated vomiting, a painful or bloated belly, a hunched posture, weakness, or a dog who will not settle. Do not offer food until you have spoken to someone.
Is a small amount of gravy really a problem?
A lick is usually a stomach upset rather than a crisis. The issue is what is in it: fat, salt, and onion or garlic from the stock. It is also rarely just a lick once people start sharing, which is how a dog ends up with a day’s worth of fat in an hour.
My cat ate a piece of string from the roast.
Phone straight away, do not pull on anything visible, and do not wait to see if it passes. Swallowed string behaves differently in cats from other objects and can do serious damage to the intestine.
Everyone is bringing their dog. Is that a problem?
It can be. A house full of unfamiliar dogs, children and food is a lot to ask of any pet. Give each dog a quiet place of their own, feed them separately, pick up food bowls and chews before introductions, and watch for the quiet signals of stress rather than waiting for a growl.
Everything seemed fine on Monday. Are we clear?
Mostly, but keep an eye out until midweek. Pancreatic inflammation tends to surface a day or two behind the meal, and the allium and grape effects lag even further. If your pet is sick more than once, or simply withdraws and stops eating, that still warrants a call on Wednesday.
