All MBK dogs are DNA tested.  We are looking for genetic defects within our dogs that could be passed down to their puppies.  Within our program, you will see 2 different results.  Either the dog will be 100% clear of any and all defects, or it may have something called "CRD4".  CRD4 is an eye condition that originated with long-haired Dachshunds, and is very common within our breed.  It is estimated that over half of our breed has at least 1 trait.  Some researches believe that this condition DOES NOT affect our breed at all.  We wrote up an article on it, so please click below to learn more!
