Ditto Rough House kennels. The old timers I talked with believed you got the hybrid vigor and abilities from the male side. A stud dog should be well built and a very strong dog. With lots of tensile strength and pulling power. Being game is still a foremost important factor.

They believed the deep gaminess traits came primarily from the bitch side. A person might buy a male dog or puppies off a dog yard. But those well producing female dogs are seldom sold. IMHO, Generally a dog yard is no better than the female dogs they were bred from. Cheers
