I was lucky not to have to make the decision with Izzy, but I did have to with my last dog, Benji. He had a large tumour on his face, which the vet assured me was causing no pain, but that he would tell me when it was time.
The aweful day came, when the tumour would very soon lift his eyelids, causing his eyes to become uncomfortable. Benji was still bright eyed and eating his food, but I didn't want to leave it too late, so we had a lovely morning in the woods, where he was allowed to chew a small branch up, followed by a huge chicken dinner and then we went to the vets.
I may be odd, but I came out of the surgery, gave Monty a hug, had a good cry and then....had a surge of happiness. I'd been able to let my lovely gentle boy go before he could have pain and that was really something.
My only guilt was that I couldn't bear to be there at the very end, but I had him heavily sedated, so he didn't know that I'd left.
I'll be thinking of you both.
Barbara, Monty, Joly and Teddy.
