This is champ. Over the past year he's become aggressive at times for unknown reasons. He has bit myself twice for unknown reasons. Looking to do the right thing and give him a chance at a rescue or someone who can dedicate more time to take care of a train him. He loves to be outside and run freely. He gets along great with my two smaller dogs but does not like new people or new dogs. Any questions please ask me. Zero adoption fees just want him to be taken care of.
