While we are normally concerned with our dogs becoming overweight, as they become older senior dogs some canines start to lose weight. Here, Our Corpus Christi vets discuss weight loss in a senior dog and when you should be concerned.
Old Dog Losing Weight and Muscle Mass
Yes, it is true that a large number of dogs tend to get chunkier as they age. In some cases, however, a senior dog can actually lose weight. The question you may be asking yourself is "why is my dog losing weight?" There are two ways that this question can be answered. Either there is an underlying condition and it's a symptom of a larger issue, or your dog’s aging requires a different balance in their diet.
Cause of Weight Loss In Senior Dogs That Are a Problem
There are roughly 8 issues that are commonly the root problem in elderly dogs losing weight. These issues are liver/gallbladder disease, dehydration, dental issues, kidney disease, heart disease, diabetes, cancer, and arthritis. Each one of these concerns needs to be diagnosed and addressed by your veterinarian. Most of these root causes will present with other symptoms that accompany weight loss.
The best thing you can do for your senior dog that is losing weight is to observe them for the other symptoms so you can inform the vet so they can diagnose your dog quicker. The symptoms that can present with each condition are as follows.

If your vet can’t find any underlying cause for the weight loss it might be time to change your dog's diet. Consult with your veterinarian about their current diet and the amount of protein, fat, and fiber they are getting. They should be able to help you find out what to feed an old dog that is losing weight but still eating.
In conclusion
If your older dog is losing a significant amount of weight, and rapidly, go to your veterinarian's office as soon as possible. If you are worried about your dog's weight in general, bring it up with your veterinarian at your dog's bi-annual routine exam.
