Winter Effects on Your Dog’s Weight: Why It Happens and How to Help
Winter can be a challenging season for dogs — from icy walks to long, lazy days indoors. But did you know that cold weather can also affect your dog’s weight? When the snow starts to fall and temperatures drop, many of us notice changes in our dogs — from lower energy to dry skin. One change that can sneak up on pet parents is weight fluctuation. Dogs may gain or lose weight in the winter depending on their activity level, metabolism, and environment.
Understanding these seasonal shifts can help you keep your pup at a healthy weight year-round.
🐾 Why Dogs May Gain Weight in Winter
- Less activity: Cold weather and shorter days often mean fewer walks, shorter playtimes, and less overall movement.
- Extra calories: Many owners add “comfort foods” or extra treats during the holidays, leading to calorie overload.
- Indoor lounging: More time spent curled up indoors = fewer opportunities to burn energy.
- Warm indoor environments: Heated homes reduce the body’s need to burn calories to stay warm, which can contribute to gradual weight gain.
Weight gain puts stress on the joints and heart, and it can set the stage for obesity-related conditions like diabetes and arthritis.
🐕 Why Some Dogs Lose Weight in Winter
Not all dogs pack on pounds. Certain dogs may actually lose weight in the colder months:
- Increased calorie burn: Dogs use more energy to stay warm, especially lean breeds or those with short coats.
- Working dogs: Huskies, shepherds, and other active breeds often stay busier in winter and burn more calories.
- Picky eaters: Some dogs eat less when it’s cold or if water intake drops.
⚖️ How to Monitor Winter Weight
- Regular weigh-ins: Check your dog’s weight monthly. Even a few pounds matter.
- Body condition score (BCS): Feel your dog’s ribs. You should be able to feel them without pressing hard, but they shouldn’t be sticking out.
- Watch for subtle changes: Struggling to jump onto the couch, a tighter collar, or less stamina on walks may all be signs of weight gain.

🍲 Tips for Maintaining a Healthy Weight in Winter
- Adjust meals: If activity drops, slightly reduce calories. If your dog is more active in the cold, they may need an increase.
- Stick to high-quality proteins: Warming proteins like lamb or beef help maintain energy while keeping meals nutrient-dense.
- Hydration matters: Dry indoor air from heaters can cause dehydration, even when dogs don’t seem thirsty. Offer fresh water often, and try moisture-rich options like warm broths, soaked kibble, or goat’s milk.
- Indoor activity: Tug games, puzzle feeders, and short training sessions keep minds sharp and bodies moving.
- Weigh food, not just eyeball: Overestimation is a common cause of weight gain.

🌷 Spring Check-In
As temperatures rise, re-evaluate your dog’s food portions and exercise routine. Many dogs naturally slim down in spring, so you may need to adjust meals again to prevent unintentional weight loss. Seasonal awareness helps maintain balance throughout the year.

Lots to think about, thanks for sharing this. I guess it's like what happens to us. Those of us who stay home more and enjoy an extra snack or three compared to those who are out and about enjoying winter sports!
ReplyDeleteI love that everything you say is in bite sized pieces. Lots of information and I don't feel overwhelmed, I can take notes! It's good to know we can be pro-active in finding the best solutions for maintaining weight and not think, 'Oh man there's nothing i can do'.. I had no idea dogs could dehydrate in winter!

My Husky often lost weight in Winter, especially when we lived in the Northeast. She was always outside burning energy!
ReplyDeleteExcellent article! I was just thinking that Henry was eating more as the weather is getting colder. He's done this every winter. But he stays very active. So, thankfully, I don't have to worry about him being overweight. But I do need to make sure I have more food on hand for him in the winter. He LOVES to jump through the snow like a big dog. I'm sharing this with all my dog parents.
ReplyDeleteWOW this is really interesting as I have never thought about this although Nili is my first dog I am battling weight problems with and battling to get her to lose her extra weight, I cannot let her put on anymore weight although living in San Francisco we only have cold and rain so walks will be ongoing. Thank you for making me think more
ReplyDeleteAnother very interesting and. informative article! I have an acquaintance whose beautiful Huskies have put on some of weight (quite portly). Hurts my heart to see as it is too much for Huskies as they are an active, fit breed. This info is great! I hope they read it when I share. Should be very helpful!
