Mastiffs with preference for English and Boerbel, Danes, Dobies (cropped is sexy but cruel so I would never do it, but it does look hot), Shepard/Husky’s = Smart and strong; Shepards = Smart, Husky’s = Stong. A mix seems to cancel out the bad in both. You get a loyal dog who listens with a strong hind end. Pit bulls are ok but very small in the pants, knot’s about the size of a squash ball. Rotties are ok but I’ve never experienced any dog that sheds more hair than the Rottie lab cross my cousin had. You’d sweep and vacuum and the next day, piles of thick, coarse black hair in all the corners of the house. I’ve always wanted to try one after seeing Loving Maggy though. I’ve had a lab, he was fun, good knot, thin dick.
