Should You Change Your Dog's Diet With the Seasons?

September 9, 2025

We change our own diets seasonally without thinking about it — lighter meals in summer, heartier food in winter. For dogs, especially those who spend significant time outdoors, similar adjustments can make a real difference to their comfort and health.

Summer: Hydration First

The biggest summer nutritional concern is dehydration. Dogs pant to regulate temperature, losing significant moisture. Signs of inadequate hydration: dark yellow urine, tacky gums, lethargy in the heat.

Winter: Calorie Adjustment

Dogs who spend time outdoors in cold weather burn more calories maintaining body temperature. A working dog in a UK winter may need 20–30% more calories than in summer. Indoor dogs in centrally heated homes may need slightly less.

Activity-Based Adjustments

Rather than strictly seasonal, calorie adjustments should track activity changes. If your dog does less exercise in winter (shorter walks, no swimming), reduce food accordingly. If they're more active in summer, increase it.

What Stays Constant

Protein quality, any breed-specific restrictions (fruit avoidance for Veldtspitz, etc.), and supplement schedules should remain consistent year-round.
