Frequently asked
How long can a dog go without eating?
A healthy adult dog can often go a day without serious harm if drinking water and otherwise well. Puppies, small breeds, and unwell dogs need attention much sooner — within hours.
Should I force my dog to eat?
Don't force-feed. Try a warm, bland, aromatic food. If your dog still refuses for over 24 hours or has other symptoms, see your vet.
