8 Vet-Recommended Dog Foods for Seniors in 2025

4.Our Vet's Pick: Best for Large Breed Seniors

Royal Canin Size Health Nutrition Large Aging 8+ Dry Dog Food
Premium formula tailored for large and giant senior dogs

When it comes to feeding large-breed senior dogs, our vet panel consistently recommends Royal Canin. This specific formula is designed for dogs over 8 years old and was described as a "top-tier dry food" by our experts.

Chicken by-product meal is the primary ingredient, offering easily digestible protein. The kibble can also be softened with water for dogs with dental sensitivities or picky appetites. It includes added glucosamine for joint support, antioxidants for immune health, and omega-3 fatty acids for brain function.

Do keep in mind that this formula is specifically designed for larger breeds and may not be appropriate for smaller dogs. It's also one of the pricier options on the list, reflecting its specialized formulation.

Things to Consider

• Created by board-certified veterinary nutritionist
• Formulated for large breeds
• Supports joint, immune, and brain health
• Must add water to make a palatable mix
