Frequently Asked Questions
How much should I feed my pet?
Just as eating amounts vary from person to person, 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. However, the feeding guide is intended only as a starting point. It's critical to your pet's health that his or her physical condition be monitored regularly and the feeding amount adjusted as needed. To access the suggested feeding guide for Hill's™ brand pet food that you feed your pet, refer to our product selector.

Feeding and Treating with Hill's™ Pet Foods
My pet is a finicky eater, how can I enhance the taste of my pet's food? Can I feed people food or table scraps?
Taste tests show that pets prefer Hill's™ pet foods to many other leading brands, however we realize some pets can be picky eaters. To help you 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, refer to the 7-Day Transition Schedule for dogs or cats. A gradual transition from the current food to a new food helps wean your pet from one food to another.
- Meal feed your pet by measuring the appropriate daily feeding amount of food and placing it in your pet's bowl. If you are feeding your pet more than one meal during the day, divide the amount into the number of feedings for the day.
- 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. Remember, food tastes much better when we have an appetite!
- If you are feeding your pet dry food, try hand-feeding by holding the kibbles of food in your hand and feeding it to your pet in small portions for the first few feedings.
- Add a couple of tablespoons of warm (not hot) water to one serving of your pet's dry food. Let the mixture sit for a few minutes to soften the kibbles, then serve. Moisten enough food for one meal feeding at a time so the food doesn't spoil. Do not leave moistened food out more than four hours.
- You can make pet food gravy to mix with the dry food by adding a few tablespoons of warm (not hot) water to the equivalent canned pet food. Spoon the gravy over the dry food and serve. Be sure to only make enough for one serving at a time so the food doesn't spoil.
- To help enhance the flavor of both dry and canned food, add a small amount of low-sodium chicken broth or the liquid drained from tuna canned in water. Only make enough for one serving so the food doesn't spoil. (Do not use this tip for Prescription Diet™ z/d™ or d/d™ pet foods.)
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.
How do I switch / transition pet foods for my cat or dog?
Pets are creatures of habit and may need some help in switching to a new food. Unless recommended otherwise by a veterinarian, gradually introduce any new food over a seven-day period. Mix the new food with your pet's former food, gradually increasing the amount until only the new food is fed.
Most pets readily accept these foods, but some are more reluctant than others to give up what is familiar to them. If your pet does not easily switch, you may want to try one of the following suggestions:
- Warming the food or adding warm water enhances the food's smell and flavor.
- Do not leave food available at all times. Consider meal feeding every three to four hours, 15-20 minutes each time.
- To help enhance the flavor of both dry and canned food, add a small amount of low-sodium chicken broth or the liquid drained from tuna canned in water when transitioning your pet from one food to another. (Do not use this tip for Prescription Diet™ z/d™ or d/d™ pet foods.)
