Hi Derry, Sincere condolences. We lost our old Newfie in identical circumstances in 2000. It was devastating - he was such a lovely dog. He's buried in the garden with his blanket and toys. Right now we are nursing our border collie through the final stages of bladder cancer. He is on medication which keeps him painfree but cannot alter the final outcome. He still enjoys his food and rooting about in the garden, the only sign that he is ill is that his bladder is constantly leaking. The house reeks of Dettol. While he is enjoying life we will keep him going. Our vet has assured us that we will know when the time has come. He estimates 3/4 weeks. This is the real price of being a pet owner, not the financial costs incurred over his lifetime, but the heartbreak at the end. As you know, only too well.
