Why Is My Senior Dog Suddenly Eating Less?

Some older dogs need fewer calories as they become less active, and changes in smell or taste may make a familiar meal less appealing. Dental pain, nausea, constipation, medication side effects, and conditions affecting the kidneys or other organs can also reduce appetite, so a new change deserves a closer look.

Check the product’s listed specifications when evaluating why appetite can change with age.

Note when the change began, how much food your dog actually eats, whether they still take treats, and whether drinking, bathroom habits, weight, or energy have changed. You can also watch for trouble chewing or dropping food, but avoid forcing a meal or changing several things at once, since that makes the pattern harder to understand.

Check the product’s listed specifications when evaluating what you can check at home.

Contact your veterinarian promptly if your senior dog suddenly eats much less, refuses food, or has a reduced appetite that continues into the next day, especially if they have a medical condition or take medication. Seek urgent veterinary help if the appetite change comes with repeated vomiting, a swollen abdomen, marked weakness, breathing trouble, collapse, or signs of significant pain.
