That's a sad story Talt but I'm glad people on here have hearts, than, let these c*nts kill animals because they don't live upto expectations or relations fall apart.

So, I don't worry all that much about it being a perfect hunter- if that makes sense?
I'm also looking to find a friend for my (previously grandad's) mum's 2yo Labrador, hoping he'd bond with the whippet
