Rio was found emaciated with his legs bound together by tape by the river. We do not know if it was someones intention to drown him or just stop him from following the people that dumped him. Many were shocked at how this poor boy had survived in the state he was in. With love and medical care he went from 14kg to 30kg. He is a strong powerful dog so he will need an owner who can handle the breed and continue his training with positive reinforcement and managed socialization with other dogs. He does run with some other well socialized dogs but he can sometimes challenge them. We feel he will be better in a household as the only dog with slow interactions to others.
