The hemangiosarcoma finally brought things to a head today, and Hank's no longer with us.

As my mom said:
Hank was such a great dog. Probably the most intelligent dog I've ever had. The vet was amazed he lived as long and as well as he did after the cancer was found. He was sure a fighter. He was trotting on the trails and chasing rabbits up until yesterday so he really enjoyed life.

He was so incredibly lucky to be living with my mom, who just made him feel like the best dog in the world in these last weeks after we found out. Tough to lose him, but it was his time, I think.
