The way i see it your an arse hole, you obviously didn't bring the dog on right if its yapping. Its brought out in a dog either entered to early or given stupid slips.... pups need to catch or they soon loose heart and become frustrated. If everyone kept and bred from shite the class of lurcher would go down hill, and we are seeing this now. So its either keep shite, pass shite around or put em down. I know which one i would choose.....If i had a dog that was opening up i would hold it back for a thew weeks then give it loads of dropped rabbits, infact id make it so the rabbit couldn't get awa
