I was in the local park today with my 4 and 6 year old children. We have a medium sized dog ourselves. She's a bit of an old lady now so just potters about having a sniff. There was a couple with a baby walking their huge XL bully dog around the park. The first time we crossed their path the dog was on a lead but their dog was pulling strongly on the lead to try to investigate either my dog, or my children. The owner was all too willing to "let the dog say hello". I'm not comfortable with huge dogs approaching my kids or my dog so I moved everyone along very quickly and didn't engage with the dog or the owners. The next time we crossed their path the dog was off lead. It wasn't acting aggressively but it bounded up to my DD. My children were playing in a small wooded area of the park where there are felled trees for them to climb. I was helping my 6 yr old DS on one bit of the logs, while my 4 yr old dd was playing a few meters away. The dog bounded up to her and she was visibly scared. The owner was making comments about how much the dog loves kids and how playful he is etc, but to me it was a huge powerful dog that was scaring my child and it shouldn't be approaching kids at all. I told the owner that his dog shouldn't be allowed to approach children and to get it on a lead away from my kids. The owner went absolutely ballistic. Telling me that he just wants to play with them, that he loves kids, that I was prejudice against American bully dogs because of the news, that his dog is friendly, that my children should be better educated in how to handle dogs who approach them in a friendly way, and that I was an irresponsible dog owner because my dog was unsupervised while my children were playing. It's true that my dog wanders around doing her own thing but she is 11, she doesn't go far, I can always see her having a sniff about, and her recall is very good. The XL Bully became very energetic in response to the owners outburst and charged at my DD knocking her the ground. It wasn't aggressive, just boisterous and spurred on by the atmosphere and the owners response to me. The owner then grabbed his dog and left very quickly, while I was left to sort out my distressed DD. AIBU to think the owners of these massive dogs should have better awareness than to let them approach kids? Was I wrong to tell the owner to get his dog away from my children? The dog was at least three times the weight of my 4 year old, if not more, it was at least as tall as her when on all fours, and she was clearly scared by this dog because as soon as she realised it was there she called out for me and backed away.
