What to consider for High Protein Dog Food For Summer Walks

Summer walks place extra demands on your dog: heat, longer distances, and potential dehydration. A high-protein diet helps maintain muscle mass and supports recovery after exercise. However, protein generates metabolic heat, so you need a balanced formula with moderate fat (12 to 18%) to avoid overheating. Look for added moisture from wet food or toppers to aid hydration. Also consider joint supplements like glucosamine and chondroitin for older or active dogs. Avoid overly rich foods that might cause digestive upset in the heat.

What to look for in a dog food

Choose a complete and balanced formula that meets AAFCO nutrient profiles for your dog’s life stage. The first ingredient should be a named meat (e.g., chicken, salmon, lamb) rather than an unnamed “meat meal.” Protein content between 22 and 32% is ideal for active dogs; fat should be 10 to 18% to provide energy without excess calories. For large breeds, ensure calcium and phosphorus levels are appropriate for bone health. Omega-3 fatty acids from fish oil or flaxseed support skin and coat health, especially in summer. Glucosamine and chondroitin are beneficial for joint health on long walks. If your dog is a small breed, smaller kibble size may be easier to eat.

How we chose these picks

  • Evaluated protein content, fat levels, and calorie density for active dogs.
  • Checked that each formula is AAFCO-compliant for the appropriate life stage.
  • Prioritized named meat or fish as the first ingredient.
  • Considered added joint and omega-3 supplements for summer activity.
  • Included a range of price points and dietary needs (sensitive stomach, grain-inclusive).
  • Verified positive reviews from owners of active dogs.
  • Never ranked a product higher just because it pays a commission.

What to avoid

  • Avoid foods with unnamed “meat meal” as the primary protein source; opt for named meals like chicken meal or salmon meal.
  • Do not default to grain-free or legume-heavy recipes without veterinary guidance due to the ongoing FDA investigation into a potential link with canine dilated cardiomyopathy (DCM).
  • Avoid all-life-stages formulas for large-breed puppies, as they may have improper calcium levels.
  • Do not switch your dog’s food abruptly, especially in summer; transition over 7 to 10 days to prevent digestive upset.
