This is typical of our family, really. 
Long story short, on Saturday, I picked up a new Border Collie. His story was that he had been from a long line of superb working dogs, he had been trained for work on the mountain with sheep, but wasn't good enough for mountain work or trialing. To stop him being shot (yes, that's very common practice within the Welsh farming community), our accountants elderly mother had agreed to take him as a "yard dog". (She has a farm). The term "yard dog" (certainly in the farming community) usually refers to a dog living it's life in a wooden kennel on the end of a chain. we were told he was a good working dog... 
He's been living on the end of a chain for 3 years. Eventually, our accountant was so fed up of seeing him permanently chained, she asked me to take him and get him into Wiccaweys. I agreed.
Then I spoke to DH. DH decided that if the dog in question is a "working dog" (i.e. a dog who was capeable of earning his living) then DH would have him - as a working dog...
Well, our new boy is wonderful. He's a huuuge BC, and he's very smiley, happy and cheerful. He gets on well with all the other animals and seems very bidable... But work? I don't think so. We have ended up with yet another cuddly dope of a dog, who gives fantastic kisses, but is shit scared of cows and sheep...
And DH has fallen in love. I suspect that our new dog won't be making it to wiccaweys after all. Especially since DH has already rung the vet to have him chipped, vaccinated and neutered... so much for DH saying "we're not having any more dogs!"
