Man that really sucks, I feel for you. We had three dogs, lost our first dog blue (tan dog) after 17 years in December. We just found out a few weeks ago our second dog Sophie (black dog) is struggling with a liver riddled with tumors. Its always a hard pill to swallow, but it helps me to know they had the best life they possibly could while they were with you!
As expressed above..I like my dogs more than most people. With that said, I am truly sorry for your loss of a cherished family member. Please consider adopting another into your home, as there are 1000's of great shelter animals, just waiting to help you fill that void.
