Dogs love food, and many seem to be hungry all the time. If your pup stares at the table during every meal, acts like they haven’t eaten in days, or begs when you open the fridge, it\u2019s easy to wonder, “Why is my dog always hungry?”<\/p>\n\n\n\n

Many dogs who seem hungry all the time are just really fond of food. But newly increased hunger in a dog can point to an issue with their diet, routine, or health. Our guide to hungry pups will help you figure out the cause of your dog\u2019s increased appetite and what you can do about it.<\/p>\n\n\n\n

What it means when your dog is always hungry<\/h2>\n\n\n\n

Veterinarians use the term polyphagia to describe excessive hunger or an increased appetite in dogs. Feeling hungry all the time can be a sign of a medical issue, but that\u2019s not the case for every dog. <\/p>\n\n\n\n

So, why do dogs love food so much? Some are enthusiastic eaters by nature, while others may carry genes that affect how their brains process signals of fullness. Recent studies in the U.K. found that 12% of Labrador retrievers and 60% of flat-coated retrievers carry at least one copy of a gene that makes them hungry all the time<\/a> while also burning fewer calories<\/a>.<\/p>\n\n\n\n

If your dog loves food and always has, it\u2019s likely that this is simply a feature of their personality and nothing to worry about, although you may need to work with your vet to ensure your dog doesn\u2019t gain weight. On the other hand, if your dog suddenly starts to eat and beg a lot more than usual, it\u2019s time to schedule a visit with your vet to check for an underlying problem.\u00a0<\/p>\n\n\n\n

Signs your dog\u2019s hunger may be health-related<\/h2>\n\n\n\n

How can you tell if your dog\u2019s hunger is related to a health problem? Usually, dogs with medical causes of polyphagia also have other signs and symptoms, like changes in thirst<\/a> or activity levels.<\/p>\n\n\n\n

Monitoring your dog\u2019s other daily habits and keeping an eye out for any changes can help you and your vet determine if your pup\u2019s increased hunger is caused by a treatable medical issue.<\/p>\n\n\n\n

Here are some signs that may accompany an increased appetite and indicate a potential health issue you should bring to your vet\u2019s attention.<\/p>\n\n\n\n

Increased thirst and frequent urination<\/h3>\n\n\n\n

Polyuria (urinating more) and polydipsia (drinking more) often go hand-in-hand with polyphagia. When all three are present, the most likely causes are diabetes mellitus or Cushing’s disease (hyperadrenocorticism, or excess cortisol). <\/p>\n\n\n\n

Weight loss or gain<\/h3>\n\n\n\n

When hungry dogs eat more yet lose weight, they may have a gastrointestinal (GI) issue such as inflammatory bowel disease or exocrine pancreatic insufficiency, which causes a lack of digestive enzymes. Diabetes is also possible, as it prevents glucose from reaching the cells where it\u2019s needed. <\/p>\n\n\n\n

When hungry dogs eat more and gain weight, low thyroid or Cushing’s disease may be to blame.<\/p>\n\n\n\n

Changes in appearance<\/h3>\n\n\n\n

Dogs with Cushing\u2019s disease sometimes develop distinctive changes in their appearance, including:<\/p>\n\n\n\n
