Frequently asked questions

Is Hill’s Science Diet suitable for dogs with food allergies?

Hill’s offers limited‑ingredient options like the Sensitive Stomach & Skin Lamb Formula that reduce common allergens. However, each dog’s sensitivities are unique, so discussing a specific allergy with your veterinarian is essential.

Can I feed a senior dog an adult formula?

Senior dogs often need fewer calories and added joint support. While an adult formula can work short‑term, a senior‑specific diet such as Hill’s Science Diet Senior Vitality provides nutrients tailored to older dogs.

How much should I feed my dog each day?

Feeding amounts depend on your dog’s weight, activity level, and the specific formula’s calorie density. Use the feeding guide on the package as a starting point and adjust based on body condition, consulting your vet if unsure.

Does Hill’s Science Diet contain grain‑free options?

Most Hill’s Science Diet lines include grains like rice and barley, which are generally well tolerated. If you need a grain‑free diet, you’ll need to look at other brands that specifically label themselves grain‑free.

What’s the benefit of L‑carnitine in dog food?

L‑carnitine helps support normal metabolism of fatty acids, which can aid in maintaining lean muscle mass and healthy weight, especially useful in formulas aimed at weight control.
