Simple ways to create comfort for an older dog

I know you have heard about our dogs and how they are such an important part of the family. You may have also heard me talk about Old Buddy Boy. He is 15 years old, maybe 16. He was abused, neglected or both before he became a part of our family. He is a wonderful dog, but can also be a moody old man if his body is hurting him. As he has aged over the last 4 years, he has actually become a friendlier, more active dog.
