Bob, that photo reminds me so much of our black Lab, it was in 1972 that we got her, we were in Australia, of course she came back to UK with us although in those days a six month quarantine was mandatory. In 1977 she developed a lump on her side which I'm convinced was the result of having been bitten by a snake, it was removed but came back two years latter, the vet arranged for us to take her to Addenbrookes in Cambridge for radio therepy treatment (We had to go in the back door :wink: ) after that she lived until she was 13 when the lump again started to grow but her back legs had gone by that time. In those days there was no pet insurance and our vet bills were high but for some reason Addenbrookes didn't charge us, I think it was because the cancer was a very rare type and the connection with the snake bite meant they could use the lump (By that time it was bigger than a cricket ball) to do research on.
Yes, pet insurance is something every dog owner should take out.
