thats the thing, he aint on about a slight yip........ a dog that yaps is a liability and a pain in the arse!!! i can remember a guy getting a pup and raising him with a pack of around 13 border terriers that him and his mates have between them..........long story short i was out with him at night, he slipped his lurcher on a big rabbit and for the min or two on it, it yapped all the time and came back all proud of itself, to an owner praising him............ would he of yapped if not raised with a bushing/ratting pack???? who knows but the dog never stopped so they just stuck to the day
