How much fat should a dog's food contain?

AAFCO minimums are 5.5% fat on a dry matter basis for adult dogs and 8.5% for puppies. Most commercial adult foods contain 10-20% fat on a dry matter basis. Active and working dogs need the higher end of that range; dogs prone to pancreatitis or weight gain are often better managed on the lower end. Always compare foods on a dry matter basis rather than as-fed percentages.

Can too much fat cause pancreatitis in dogs?

Yes -- high-fat meals, particularly rich or fatty human food given as a treat, are a well-recognized trigger for pancreatitis in susceptible dogs. Dogs with a history of pancreatitis should stay on a consistent lower-fat diet and avoid fatty extras. Acute pancreatitis is a veterinary emergency.

Should I give my dog fish oil for omega-3s?

Fish oil can be a useful source of EPA and DHA omega-3 fatty acids for dogs, particularly those with dry skin, coat issues, or joint problems. However, appropriate dosing varies by the dog's size and health status, and too much can cause side effects. Ask your vet for a dose recommendation before starting supplementation.

Is a low-fat diet good for all dogs?

No. For healthy dogs, very low fat can impair absorption of fat-soluble vitamins and compromise skin and coat health. Low-fat diets are specifically indicated for dogs with pancreatitis, fat malabsorption conditions, or hyperlipidemia -- and even then, the restriction level should be guided by a vet rather than chosen arbitrarily.
