Be Alert to Changing Needs  As your dog ages, his needs will change. He may require a different diet, need more sleep, and be less active. Do what you can to keep him comfortable. Your dog may not be as "fun" as he once was, but he is the same dog you loved as a puppy. You should do everything you can to pamper him in his final years.

End Suffering  If, due to illness or old age, your dog reaches a point where his quality of life is severely compromised, arrange to end his life humanely. Letting go is sometimes the kindest thing you can do. Don't prolong the suffering because you fear the pain of losing your dog.
