My 14-year old Black Lab lost his long battle with cancer. He was one of those rare animals that I established that 'special bond' with. Damn, I really miss him. Taking him to the vet for the final visit was probably the hardest thing I've ever done.
The love in those big, brown eyes is something that cannot be replaced. Before he left this world, I told him that in the next life I would be the dog and he can be the master.
Moral of the story - enjoy your family and 'friends' while they're here......
Peace and good health to all
