 By doing such, your dog will be able to enjoy rawhide bones and chew toys like he did when he was enjoying them as a puppy. And remember this. As our dogs get older, they need exercise as well. Just because they become a fixture in the house, don't forget to teach them a new trick. Take them for a special walk or ride in the car to the beach. Mental stimulation will keep your dog happier and living a bit longer. I'm Warren Eckstein.
