HELP! Recent aggression?
okay my dog isn't a pure breed shepherd. He's a rescue dog I found when I was helping clean up after tornadoes came through Alabama. He's a shepherd/husky/lab mix according to the vet, his guess was that he was about 6/8 months when I found him and that was almost 2 years ago... He has ALWAYS been a happy, loving, playful dog! The only person he ever growled at was my step dad which was in a completely protective way. He did bite him but it was to protect me because he got to close to me and jack didn't like it. (My step dad is now spending 25 years in prison so it was warranted.) anyways a few months ago if anyone approached him while he was eating he would growl and be aggressive (we have an inside dog and if you opened the door the small dog would come to it doin didn't think much of it) .. Now it's sporadic. It can happen at anytime but mainly with me! It's happened once with my cousin but never a stranger. His hair stands up and he starts growling. He LOVES car rides so I took him on a trip and he acted fine until I stopped to get gas on the way home and I went to pet him before I got in the car and he bit me... Not enough to break the skin but enough to bruise me... I can just look at him and he starts growling... I don't know what to do... I absolutely LOVE this dog but if he continues this I can't keep him... Any and all advice is appreciated.
*this dog has rarely ever had to be gotten on to, he's very well mannered and sits and lays down through silent gestures I make different signals with my hands and he obeys, if he's excited I'll have to use verbal but rarely... Also I'm sure he used to be a house dog and was fine in the house until I moved as he has a back yard to play in and I didn't want him cooped up all day but I moved a year ago so that's not a recent change.. This dog has even literally saved my life twice... I don't want to get rid of him but if he bites I can't trust him.
