So, with school starting, there are some parents who bring their dogs along in the morning to drop off their kids. Now, I don't mind dogs, but there is one mum who leaves her big German Shepherd tied up at the gate. Again, I don't mind dogs, but this one barks, whines, and lunges at other dogs/kids. The school has already put out a newsletter asking parents not to bring them, as there are children who may be frightened. Today, it lunged at another dog and there were children around. I'm not sure if I should let this slide, or say something to the school, or wait a few weeks? It seems unsafe to me. AIBU? Even my five year old shies away from it, and he's generally okay with dogs.
