This looks like a job for *Super Nancy*!

Thankfully nobody was hurt.

One guy at the dog park has 2 Rotties and a Gr. Dane. Another guy has a Boxer.

There could be 35 dogs in the park but the mini-second that the Rotties see that Boxer...let's put it this was..somebody is told to leave, regardless of who arrived first. I haven't seen the guy with the 3 dogs in ages. My guess he was asked not to come back. I could never figure out if it's a smell, attitude, physical appearance. It was, well, odd and scary as he$$

I know you feel awful. Hope Nancy can help.
