Hill’s Science Plan Adult Sensitive Stomach & Skin Medium Dry Dog Food is for dogs with allergies or sensitivities that affect both their internal and external health. It’s ideal for medium size adult dogs (11 – 25 kg) who have sensitive stomachs and may not be able to handle a broader spectrum adult dog food. The food supports digestive health, promotes a healthy skin and coat, and the prebiotic fibre offers relief to the digestive tract.
