I'm late in posting to this thread because I just joined today but I had to chime in to tell you how sorry I was to hear about your two dogs, Rowdy and Crash. I believe we live in parallel universes. Both my dogs Otis and Pickle Juice died one week apart back in September as well. The even more coincidental thing is, Otis had lung cancer. The first time he had it, it was the size of a football so I had that lung removed. 2 years later the cancer grew back in the same spot but this time it was stuck to his rib since there was no longer a lung there. It was huge and inoperable. He was in pain by the 3rd month after it had come back so I put him to "sleep". He was 17 years old. A week later my 11 year old dog, Pickle died mysteriously. I feel your pain Jim.
