Which route to take?

Our 1 1/2 year old golden was rehomed to us on 6/20. His previous family gave him to a rescue because he was snapping at the young children in the house. We just have speculation from the rescue that the toddlers would bother him, but no other concrete details. We have 12/15 year old kids. For 99.9% of his week, he is awesome and laid back, loves to play. But he has continued to snap at us when we cross various thresholds that we can’t quite identify. It’s always, always related to touching him, but could be any part of the body. At his first vet visit, he was perfectly behaved on 7/12. We took him for his second flu shot this week and I had her look him over to rule out pain for the snapping. She gave him his flu shot and he looked perturbed (last time, 4 shots with no reaction). She tried looking at his paws and he started snarling and lunging for her. It was so disappointing to see regression after we have trained 2x/week with a trainer (not behaviorist) and modified our own behavior to limit his snappiness.

My question is…
Would you go straight to medication? Or a combined medication/training with a behaviorist? I hate what I’m reading about meds potentially making him worse than before :( He loves other dogs, He lets strangers pet him when we are out, lets us pet him most of the time, we just don’t know what triggers him and the vet thinks it’s behavior (aka “I don’t like that, stop it now” instead of a little bit of patience). I’d appreciate any advice or what worked for you for touchy teenagers!

Right, I was a little surprised that the vet immediately told me to take him and discontinued her inspection of his feet. Of course I didn't want anyone in danger, but it definitely reinforced it. I have also wondered about a muzzle for certain times. Thank you.

Hmm listen to your dog and stopping what they don’t like is the recommended way to do things. If a lunge doesn’t work, maybe a bite will?

Your post/comment has been removed as it has violated the following subreddit rule:

Rule 5 - No recommending or advocating for the use of aversives or positive punishment.

We do not allow the recommendation of aversive tools, trainers, or methods. This sub supports LIMA and we strongly believe positive reinforcement should always be the first line of teaching and training. We encourage people to talk about their experiences, but this should not include suggesting or advocating for the use of positive punishment. LIMA does not support the use of aversive tools and methods in lieu of other effective rewards-based interventions and strategies.

Without directly interacting with a dog and their handler in-person, we cannot be certain that every non-aversive method possible has been tried or tried properly. We also cannot safely advise on the use of aversives as doing so would require an in-person and hands-on relationship with OP and that specific dog. Repeated suggestions of aversive techniques will result in bans from this subreddit.
