Christmas Food Dangers for Pets

One of the best parts of Christmas is the food, and with all these delicious treats being handed out, it’s only natural for dogs to want in on the action.

While sneaking your dog a little slice of turkey may not do any harm, some Christmas foods are toxic to our pets and cause severe internal damage and even death if ingested.

Chocolate
It’s well-known that chocolate is toxic to dogs, and while it may not always be fatal if ingested, it can cause serious illness as it contains the chemical theobromine. Neither cats nor dogs can metabolise theobromine as well as people can, which means they are far more sensitive to the effects this chemical has as a heart stimulant, blood vessel dilator, and smooth muscle relaxant.
Christmas Puddings & Mince Pies
These festive treats contain a variety of dried fruits such as raisins and currants. Grapes alone are toxic to dogs, and some evidence has shown they are toxic to cats as well, and dried fruits are thought to be even more so. Always make sure you keep all christmas treats containing dried ruits far from reach, such as in a high cupboard.
Onions
Onions (as well as garlic, leeks, shallots and chives) are part of the allium family, which are known toxins for pets as they contain a chemical called N-propyl disulfide, which can damage your pet’s red blood cells and lead to life-threatening anaemia. Onions are toxic to pets in any form, including fresh, fried and even powdered, and are used in various festive foods, including stuffing and other dishes. It only takes 100g of onion per 20 kg of body weight for your dog to suffer these severe effects.
Alcohol
While alcohol isn’t exactly healthy for humans in high volumes, alcoholic beverages in any capacity are dangerous to cats and dogs. Ingesting alcohol can cause a dangerous drop in your pet’s blood sugar, blood pressure, and body temperature and can even potentially lead to seizures or respiratory failure. Never give your dog or cat alcohol in any form, including any foods that contain alcohol.
Macadamia Nuts
Macadamia nuts are a common ingredient in many baked goods throughout the year, but they’re also listed as one of the top toxins for dogs. They can cause diarrhoea, vomiting, tremors, and fever. While it’s unknown what causes this reaction in the macadamia nut, and it doesn’t seem to affect cats, it is best to keep any food containing macadamia nuts out of reach of any pets in your household to be safe.
Leftovers
It can be tempting to reduce food waste by offering Christmas leftovers to your dog, but you should avoid doing so as they could contain any one of the above-mentioned toxins as well as any other known food toxins to your pet without you realising it. Make sure all leftovers are kept out of your pet’s reach, and if you do want to offer them something special on Christmas day, stick to cat or dog treats or offer them some skinless and boneless turkey that hasn’t had any cross-contamination with stuffing or other toxic additives.

Toxic Festive Plants

Nothing beats decking the halls with Christmas decorations and plants, but some of these things can be more dangerous to your pets than you realise.

Many indoor plants are toxic to pets, and these festive ones are no exception.

Mistletoe
This shrub is a popular Christmas decoration. While certain parts of the plant are not toxic, some are, and it’s always better to be safe than sorry when it comes to your pet’s health. Some animals that ingest parts of the mistletoe plant may not show any signs of poisoning, but others can show common poison symptoms such as drooling, vomiting, and diarrhoea.
Poinsettia
This lovely, leafy Christmas plant is a member of the euphorbia family, which are well-known toxic plants, and poinsettia has a particularly high reputation for being toxic to pets. The sap, in particular, can cause pets to drool or suffer mild vomiting or diarrhoea if ingested.
Holly
Holly is a very popular Christmas decoration, and its most obvious danger is the sharp-edged leaves, which can puncture the delicate insides of your pet’s mouth and will likely stop them from eating too much, but it can also harm your pet. Holly berries have toxic effects on pets that result in irritation in your pet’s mouth, vomiting or diarrhoea, so it’s best to avoid having real holly in the home during Christmas.
Ivy

This plant is a popular indoor choice because of how the branches and leaves hang down. Still, it is also a standard inclusion in Christmas decorations, particularly wreaths or other displays.

Ivy is toxic to most living things because it contains saponins and polyacetylene compounds. However, pets and children are at much higher risk of poisoning from either ingestion or touch. Ivy can cause stomach upsets and even severe skin irritation or allergic dermatitis.

Christmas Trees

Many types of Christmas trees have relatively low toxicity to pets. However, the natural oils in the needles can irritate your pet’s mouth and stomach and vomiting, drooling, and diarrhoea may occur if ingested. Pine needles are also small and sharp and can easily cause damage to your pet’s mouth and throat if eaten or swallowed, or prick their feet if trodden on once the needles fall off.

Christmas trees can also be a real temptation for cats, who are easily tempted by the twinkling lights, hanging decorations and the innate need to climb.

While we’ve talked about the things that are outright toxic to your pets, there are several other things you should be wary of this Christmas that can be hazardous to your pets, including:
