For dogs, meat proteins represent a large part of their diet, along with fruits and vegetables. One of the functions of protein in the dog’s body is to build and maintain muscle tissue.
In other words, older dogs lose muscle mass and need more protein in their diet to maintain this tissue.
When a dog starts to lose muscle tissue, the dog’s immune system is compromised, making the animal more susceptible to disease.
In addition, the dog decreases its physical strength, affecting its energy levels and mobility.
For that reason, experts recommend at least 25% protein daily caloric intake for senior dogs.
This way, your older dog will maintain his strength for longer.
