Quick answer
Our top pick is Purina Pro Plan Weight Management with Probiotics. It combines low calories with added probiotics to promote stool firmness. For dogs with sensitive stomachs, Hill’s Science Diet Sensitive Stomach & Skin is a strong runner-up. Both are widely available and backed by AAFCO feeding trials.
What to consider for Low Calorie Dog Food For Loose Stools
When choosing a low-calorie dog food for loose stools, look for controlled fat content (8 to 15% on a dry matter basis), moderate protein (20 to 30%), and a balanced fiber source such as beet pulp or pumpkin. Probiotics or prebiotics can help stabilize digestion. Avoid foods with excessive fat or unnamed meat meals, which may worsen stool quality. Always transition gradually over 7 to 10 days.
What to look for in a dog food
Ensure the food meets AAFCO nutrient profiles for your dog’s life stage (adult maintenance or growth). The first ingredient should be a named meat source (e.g., chicken, lamb, salmon). Protein should be between 20 and 30%, fat between 8 and 15% for weight management. For loose stools, look for added fiber (3 to 5% crude fiber) and probiotics. If your dog is a large breed, choose a formula with controlled calcium and phosphorus. Omega-3 fatty acids from fish oil can support skin and coat health.
