DDRPROGSD1's video: GSD ON DEAD ROAD REHABILITATION MAVERICK V 1

I have this dog for a week, the day I saved ham it was the same day he had an appointment with the vet to be put to sleep. Without provocation he attack his on owner more than once by sending ham at the hospital for a surgery and he launched himself against family members biting the wife and daughter as right now is dangerous and not stable. Maverick he's a mix GSD and is 2 years old and "knows" only two commands but what I noticed every time I gave him commands (in English) he became very very aggressive certainly bad memories from the past so I decided to teach him a good behavior in a different language to neutralize his past that I do not know completely and these are the results without using leash or collar and from behind the kennel.
