Older Dog's Weight
It's commonly believed that as dogs get older, they tend to gain weight. However, some dogs may experience weight loss instead. If you're wondering why your dog is losing weight, there are two possible reasons. Firstly, it could be a symptom of an underlying health condition or illness. Alternatively, it may be due to your dog's changing dietary needs as they age.

There are eight common issues that can cause weight loss in elderly dogs. These include liver/gallbladder disease, dehydration, dental problems, kidney disease, heart disease, diabetes, cancer, and arthritis. It is important to have your dog examined by a veterinarian to determine the underlying issue. In most cases, these issues will also present with other symptoms in addition to weight loss.
