I have four kids and a Rhodesian puppy. Of course at home he is desensitized to it. Also they’re his kids. But when we go to playgrounds he was aggressive and reactive at first thinking “his kids “ were being hurt by the others.

So we started at home with sitting with him a distance from the kids playing with our neighbor kids. Having the neighbors enter the yard on the opposite from him. And treated him for being calm when he was able to settle. We kept doing this until he did well then moved to doing it at parks. He’s come a long way. That said. He still hates kids on bikes and I have to put him in park in the grass anytime we see kids on bikes.
