Im very sorry to hear it didnt work out too. I totally understand where you are coming from, Mathew my 7mth whippet puppy is having to go back to his breeder this week too.

Its horrible feeling like such a failure and wanting desperatley to try to make it work even knowing you will just make everyone miserable instead. Adam has started attacking Mathew, wether coz he is too big and threatening or just coz he doesnt want another boy around I dont know.
I know, like Lina, they get on wonderfully at times but you sometimes cant take the risk that they will blow up and seriously hurt each other..
At least she has another loving home to go to..
