While we are normally concerned with our dogs becoming overweight, as they become older senior dogs some canines start to lose weight. Here, Our Stroudsburg vets discuss weight loss in a senior dog and when you should be concerned.

Old Dog Losing Weight and Muscle Mass

While it is true that a large number of dogs tend to get chunkier as they age, some senior dogs start to lose weight. The question you may be asking yourself is "why is my dog losing weight?" There are two categories that this answer can take either there is an underlying condition and it is a symptom of a larger issue or your dog’s aging process requires a different balance in their diet.

Cause of Weight Loss In Senior Dogs That Are a Problem

There are eight issues that are frequently the root cause of weight loss in elderly dogs. These problems include liver and gallbladder disease, dehydration, dental problems, kidney disease, heart disease, diabetes, cancer, and arthritis. Your veterinarian must diagnose and treat each of these problems. The majority of these underlying causes will manifest as other symptoms associated with weight loss.

They should be able to advise you on what to feed an elderly dog who is losing weight but still eating.
