Holiday Hazards - December 2025

Friends of the Cornell Riney Canine Health Center,

As the year draws to a close, many of us will spend time gathering with friends and family to celebrate the holiday season. Of course, it’s only natural to want to include our dogs in the magic of the festivities. Before we get too carried away, I’d like to take a moment this month to review some holiday traditions that can pose risks to our pets.

Holiday foods

I love to cook and bake this time of year, and my dog Mishka always keeps close tabs on the kitchen just in case something comes her way. But one of the most common problems veterinarians see around the holidays is food-related illness—whether from toxic ingredients or upset stomachs caused by rich or unfamiliar foods.

The big offenders this season include chocolate, raisins, grapes, onions and garlic, all of which can be toxic to dogs. Sugar-free candies and baked goods containing xylitol are another serious risk, as it is an ingredient that can cause life-threatening drops in blood sugar.

Even foods that aren’t strictly “toxic” can cause trouble. Fatty, salty, or sugary foods—like turkey skin, gravy, buttery foods, or dessert scraps—can lead to painful gastrointestinal upset or even pancreatitis, which sometimes requires hospitalization. Meat bones should also be avoided, as they can splinter, damage the digestive tract, or break teeth.

Many dogs get into trouble not because they were given these foods, but because they found a way to steal them. From counter-surfing to sneaking food out of the trash, a determined dog will find an opportunity if it’s available. Make sure food is never left unattended, trash is secured and everyone in the household (and your guests!) knows the rules: no table food for the dog.

If you’d like your pup to share in the celebration, prepare a safe, dog-friendly treat instead. Holiday flavors like plain pumpkin puree, cooked sweet potatoes, lean unseasoned turkey breast, apple slices, plain unsweetened applesauce, string beans, peas, or baby carrots are all festive and safe options. (Mishka is particularly fond of peas and green beans!) As always, treats should make up less than 10% of your dog’s daily calories, and when in doubt, check with your veterinarian before offering something new.

Decorations and seasonal hazards

The sparkle and charm of holiday decorations can be irresistible to dogs. Unfortunately, tinsel, ribbons and ornaments can be very dangerous if chewed or swallowed, potentially leading to intestinal blockages that require surgery. Holiday plants such as holly, mistletoe and lilies are toxic, while even the water at the base of a Christmas tree may contain harmful chemicals or bacterial overgrowth. Electrical cords from string lights, candles and batteries also pose serious risks of burns or poisoning if chewed or knocked over.

The best prevention is management. Creating a pet-safe zone in your home where your dog can’t access tempting decorations is often the best solution. This is especially important for puppies that are little explorers and bound to get into trouble without the proper management in place. Using items like baby gates, exercise pens, free-standing gates, or even leashes in the house, when necessary, can help keep pups safe and out of trouble by blocking off certain areas, such as a Christmas tree, while still enjoying your festive home.

Managing stress

The holidays bring joy, but also noise, guests and disruptions to routine. For many dogs, this can mean stress or anxiety. Sticking to familiar schedules—regular walks, meals and quiet time—provides stability. Offering a cozy retreat away from the bustle can give your dog a much-needed break.

If your dog is especially nervous with strangers or loud gatherings, talk to your veterinarian about options ranging from behavioral strategies to calming supplements or prescription medications.

Holiday travel

If your holiday plans involve travel, think ahead about your dog’s care. For dogs staying home, book a trusted sitter or boarding facility early. If your dog will be joining you, bring along familiar items like bedding or toys, and make sure they’re safely secured during car rides. Frequent breaks for water and exercise help make the trip smoother for everyone.

Even with the best precautions, accidents can happen. If your dog eats something concerning or develops signs of illness such as vomiting, diarrhea, lethargy, or loss of appetite, contact your veterinarian right away. Prompt action can make all the difference in ensuring a good outcome.

Wishing you and your dogs a happy, healthy and safe holiday season. Thank you for being a member of the Riney Canine Health Center. We look forward to catching up with you next month.
