Hi everyone! I'm at a total loss of what to do here. I adopted a 6 year old Chi mix a little over a year ago. He's been a total lovebug towards me, but is a little wary of new people. He was very badly abused before I adopted him, and that's evident in his behavior, but overall he's a really well behaved, sweet pup. A few weeks ago, he started growling and barking teeth anytime I go near him. Not with other people, just me. He's still totally obsessed with my parents. I ruled out any medical issues with my vet, he's in perfect health. He'll jump up on the couch with me and lay on my lap, but if I touch him, all bets are off. Does anyone have any advice on what this could be? I'm worried because it's completely out of his behavior.
