When Willow got lymphoma in January, 1999 and I dropped her off at the vet for "observation", it was the last time Max ever saw the friend he had known for almost 10 years. She died that night at the vet. Max grieved deeply until I brought home Dot, another greyhound, about 3 months after Willow passed away. A few months later, I had to visit family back east and dropped Max and Dot at the same vet for boarding. While they were there, I had Dot chipped. The staff told me afterwards that, when they took Dot away for the chipping, Max, my big, brave German Shepherd Dog, started to cry and whine and didn't stop until they brought her back to the kennel. I really believe he didn't expect to see her again.
