Mush i had the exact same problem! i had a bedo whippet and it was a lovely dog around the house and on the park but as soon as it had a sniff of any quarry it was gone and took an age to come back, sadly i got rid, it was no use wat so ever, However i was only 13 at the time, rong dog to start me off, i learned from my mistakes then Got meself a collie/greyhound whippet, a lovely natured dog, a good worker, shows plenty of gameness, but has very brittle bones, and constantly knocking herself up, she sadly retired due to dislocating her leg, but 2 months ago, i got myself a collie/greyhound,
