Quick Rules to Remember
- Diet first: a complete and balanced food covers most needs; supplements are extras.
- Fresh water always: about 1 ounce per pound of body weight a day is a common guide.
- Watch for red flags: repeated vomiting, blood, a swollen belly, weakness or not drinking need a vet.
- One change at a time: it makes it easier to see what helps or hurts.
Frequently Asked Questions
What are the basics of dog nutrition?
Dogs need protein, fat, carbohydrates, vitamins, minerals and water in the right balance. A complete and balanced food for your dog’s life stage provides them; human food and treats should stay small extras.
When should I call the vet about my dog's stomach?
Call if vomiting or diarrhea lasts more than a day, there is blood, your dog stops drinking, or seems weak or in pain. Call right away for puppies, seniors and dogs that ate something toxic.
Does my dog need supplements?
Most healthy dogs on a complete diet don’t. Fish oil or joint supplements can help some dogs, so ask your vet first.
