Old Dog Losing Weight and Muscle Mass
Some dogs start to lose weight as they get older, despite the fact that it is true that many dogs become chunkier as they get older. You might be wondering, "Why is my dog losing weight?" in this situation. There are two possible explanations for this answer: either there is an underlying condition and it is a symptom of a larger problem, or the aging process of your dog requires a different balance in their diet. Both of these explanations are possible.
Causes of Senior Dogs Losing Weight That Are a Problem
When it comes to weight loss in senior dogs, eight different problems are frequently the leading causes. Dehydration, dental problems, kidney disease, heart disease, diabetes, cancer, and arthritis are some of the conditions that fall under this category. Other conditions include liver and gallbladder disease. Your veterinarian is the veterinary professional who should diagnose and treat each of these issues. In the majority of cases, these underlying causes will present themselves as other symptoms that are associated with weight removal.
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.

What to Do If No Underlying Medical Issues are Causing the Weight Loss
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 can give you advice on what to feed an old dog that is losing weight but is otherwise eating.
In Conclusion
