How much should I feed my pet?

Just like people, eating amounts vary from pet to pet. Most Hill's pet foods have a feeding guide on the package to help you determine the proper amount to feed your pet. Please keep in mind that the feeding guide is intended only as a starting point, and you should follow your veterinarian’s recommendation based on your pet's specific health needs.

Feeding and treats

My pet is a finicky eater, how can I successfully switch their pet food?
In this situation, we suggest following one or more of the tips below to encourage your pet to eat.

If you are starting to feed your pet a new food, a gradual transition from the current food to a new food helps wean your pet from one food to another.

For dogs, allow 10-20 minutes for your dog to eat, then remove the remaining food and wait to feed your dog until his next meal.

If you are feeding dry pet food, try hand-feeding the kibble from your hand in small portions for the first few feedings, like a treat.

Here are some additional resources that can help you successfully switch your pet’s food:

Should I feed my pet people food or table scraps?

We do not recommend feeding people food or table scraps. Veterinarians strongly believe that feeding pets table scraps or "people" food can lead to excesses or deficiencies of nutrients in your pet's nutrition which over time may lead to health problems for your pet (like obesity). Feeding table scraps or “people” food can also result in a more finicky pet.

About our company

Our Mission is to help enrich and lengthen the special relationship between people and their pets.

We believe all animals from your pet, to the companion animals we care for should be loved and cared for during their lifetimes.

More About Our Mission
Are your dog food or cat food bags recyclable?

Many of our bags are made out of #4 Low-Density Polyethylene (LDPE) plastic — one of the most recycled plastics. LDPE can be turned into all kinds of new things, including construction materials and new packaging. Our plan is to continue the rollout of recyclable packaging across all of our brands and across other parts of the world — just one part of a larger 2025 environmental strategy from our parent company, Colgate-Palmolive.

See Our Sustainability Plan
Are your dog food or cat food bags biodegradable?

No, these bags (and plastics in general) are not designed to be biodegradable. The #4 LDPE plastic used in our bags is designed to be "circular," so that the material can be re-processed into new products and packaging.
