Your dog's diet should be one of the first and more important dog care needs you have. But, do not be fooled into believing that those very expensive products are the best for you. Instead, look at the label. Protein should be one of the first things listed there. While inexpensive food care products are not the best either, look for a middle ground.
Dog care surrounding your dog's weight is important. A visit to your veterinarian should provide you with the information you need. You should be looking at his age and weight combined. The older a dog gets, the more difficult it can be for them to manage being overweight. Work closely with your vet to improve his diet.
