Weight loss in dogs isn't the most common concern but when it comes to older pups, it can become a challenge for pet owners to help them maintain a healthy body weight. Our Tumwater vets explain.
How Dogs Weight Changes As They Age
While it is far more common for dogs to gain weight as they get older, some do start to lose weight as well. The question though, is why they are losing weight and how to stop it. 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.
