So the backstory is that every monday me and my dog (3 years) attend a club where it's mostly elderly and a couple of dogs that get along with my dog, yesterday we went as usual but instead of the two familiar dogs there was a new dog. A very energetic puppy (8 months). My dog tends to avoid new dogs in rooms so I figured she'd be fine as long as the puppy listened to her warnings. Has worked before. But this time it didn't, the puppy kept chasing my dog and my dog being smaller than the puppy she got very agitated and ended up jumping on my lap for safety. I was preparing to leave while holding my dog when the puppy started jumping at me and that's when my dog snapped and tried to bite the puppy. She couldn't reach obviously but she did snap. After which the owner of the puppy got mad at me and my dog for this behavior. To note the puppy had been chasing and annoying my dog for like 15 minutes nonstop and only then did my dog snap. The owner of the puppy ended up leaving right away and when I set down my dog, who likes the owner of the puppy, and she went to say bye to the owner, the owner yelled at her not to get near. This been bothering me all night.
So question is, what could I have done differently to somehow prevent my dog from trying to bite this puppy? We have our issues on walks but never before in the clubroom because she's been to there since she was a puppy nor have we had issues to this extent with puppies.
