Yes, I too, can appreciate your loss.
We lost our beloved 15 year old silky terrier to a hit and run driver in a bad storm five years ago. She had got out of the yard and after looking for her in the streets in the middle of the night during the storm (and waking the neighbours), I got a call from our vet at day light to inform me someone had taken her in to him and she was badly injured.
The vet was wonderful, but he could not save her. And as terrible as it was for Topsy and for her human family, I could never have made the decision to put her down voluntarily from old age because at 15, she was not a young dog and I am only grateful that she did not have to suffer for too long.
We had just laid my grandfather to rest the day before the storm, so it was a double blow.
My sister has just given me a new puppy this week, as it is the last litter of pups her black poodle is having. This new puppy is also black, hairy, intelligent and friendly. So, this could be interesting.
Best regards...
