Hi everyone,
I have inherited a white male German shepherd with behavior problems I Have never seen nor heard of. His name is Prince and he is 4 ish years old, never neutered and has been confined in a pen about 10'x14. He has never been trained or socialized. He belonged to my elderly mother in law who wanted him as an alarm and she was unable to do anything other than throw in food. I have been trying to work with him first on a leash....so when I take him out he starts this extreme spinning and biting his rear first one direction then he will turn and spin the other direction biting til his tongue is bloody...it becomes intimidating as he is unpredictable. If I let him out unleashed he'll run around snifffing and peeing like a normal dog with fewer incidents of the spinning and biting.. Anyone have any experience with this type of behavior or ideas for resolving this behavior.....nor sure if the trigger is leash or getting out of his pen?????
