Not only can old dogs learn new tricks; they can teach us a thing or two about the value of age and experience and unconditional love.
Bella always got compliments wherever we went. She had long, collie/shepherd fur flecked with gold, red and gray tones that glistened as she played with the waves on the beach or showed off her tricks for the neighborhood children. I started to see the problems about six months before she needed full-time help walking. Her spirit was willing, but her spinal degeneration was rendering her back legs weaker and weaker in a relentless march toward immobility, much like the way Multiple Sclerosis can progress in some people.
