Aint seen many beddy x's work, but of the ones I have seen, none of em yapped. I don't believe any x or type is more prone to yapping than any other type, but rather it's the owners that run em too young or unfit, or more than likely both, and also overwhelming the youngster with stupid impossible slips, rabbit too close to cover etc, too far away for youngster to gain ground on it or whatever. Worse dog for yapping I've seen was a bull/grey x collie/grey, make that of what you will
