i have owned a full brother to this dog and bought it from this dogs owner. it was unable to learn something as easy as sit.i spent $1900 in training to this breeder and trainer. the dog did not learn anything.it would also try to bite children. the owner MIKE MEYER gave me a 6 week old pup out of york. this bitch is now 2 years old and loses her hair all the time. the vet cannot find anything that is causing it.her ears point outward. i called the owner and he would not refund any money,replace the female,or offer any help.
