10 Best Dog Foods For Allergies 2025 in the United States

Purina Pro Plan Sensitive Skin and Sensitive Stomach Dog Food Lamb and Oat Meal Formula is specially designed for adult dogs with sensitive stomachs and skin issues. It uses real lamb as the main protein source, which is beneficial for dogs that may react poorly to more common proteins like chicken. The formula includes oatmeal, a gentle grain that is less likely to cause allergic reactions compared to wheat or corn, making it a grain-inclusive option that's still easy on digestion.

This dog food stands out by containing live probiotics, which help support healthy digestion and immune function, a key factor for dogs with sensitive stomachs. Additionally, it includes sunflower oil rich in omega-6 fatty acids, which can promote a healthy skin and shiny coat. However, it does not contain hydrolyzed protein, which some hypoallergenic diets use to minimize allergic reactions, so dogs with severe protein allergies might need a different option.

This dog food suits most adult dogs with mild to moderate sensitivities rather than those with severe allergies requiring prescription diets. It is recommended to introduce it gradually to avoid digestive upsets.

Purina Pro Plan Sensitive Skin and Stomach Dog Food is a solid option for dogs with allergies or sensitive digestive systems. One of its key strengths is the use of real salmon as the primary protein source, which is less likely to trigger allergies compared to other proteins like beef or chicken. The formula includes easily digestible oatmeal, making it gentle on the digestive system. Sunflower oil in the ingredients adds omega-6 fatty acids, which are beneficial for maintaining a healthy coat and skin.

Additionally, the inclusion of live probiotics supports digestive and immune health, making it suitable for dogs with sensitive stomachs. However, it is worth noting that this food is not grain-free, which might be a concern for dogs with specific grain allergies. It does not use hydrolyzed protein, which could be a drawback for dogs with severe protein allergies as hydrolyzed protein is pre-broken down to minimize allergic reactions.

Despite these minor issues, this dog food is suitable for adult dogs of all breeds who require support for sensitive skin, digestive health, and immune support.

Hill's Science Diet Sensitive Stomach & Skin dog food is designed for dogs with sensitivities, offering a chicken-based protein source that is easy to digest. This formula includes prebiotic fiber, which promotes a healthy gut microbiome, and omega-6 fatty acids and Vitamin E to support a healthy coat and skin.

As a grain-inclusive option, it may not be suitable for dogs with grain allergies, but the use of high-quality, globally sourced ingredients made in the USA adds to its appeal. Although it does not contain hydrolyzed protein, which can be a drawback for dogs with severe allergies requiring extensively broken-down proteins, the large 30-pound bag size offers good value but may be cumbersome for some pet owners to handle.

It is best suited for adult dogs aged 1-6 years and is formulated to meet their nutritional needs effectively.
