I just saw this - I also hope Giselle heals quickly. You did the right thing, & it sounds like they are good owners. Hope the meet-up goes well.
You mentioned that you need to tell him Ivy can never meet a dog off leash- just be sure he understands she is NOT dangerous. Somehow wanting to keep Jack away from small dogs (which he wants to play "gotcha" with) has been misconstrued & last week a guy with an Eskie asked me which one of my dogs was "the mean one." MY jaw dropped open. "Neither" I said.

We were only attacked on a walk once, by a golden, not a breed I would expect to be aggressive! When we got home, I noticed a puncture wound on the underside of star's jaw. I called the dog warden, not to press charges, but to check if the other dog was up to date on immunizations. He came out, checked Star & Rosie, then the other dog, it was up to date. He told them if it happened again they would be required to tie their golden and not rely on their invisible fencing, which obviously didn't prevent the dog from leaving the yard. Thankfully there were no vet bills, but I'm pretty sure they would have paid them.
