While the breed itself is prone to such issues, getting a puppy from a breeder who health screens the parents and has the elbows and hips certified and rated can significantly reduced that chance.
Most breeds have some type of chronic issue, and there is always just bad luck such as my Mollie who recently passed away. You'd still have that same chance with a mutt, but without knowing what kind of drive it protective instincts the dog would have.
Picture of my new pup just because.
