no harm in complaining to the park warden if there is one.
I hope that you feel calmer soon.
I hate it when people allow their dogs to run at and jump on people who have no idea if the dog is safe or not.
I had a dog run up to me and little CRX on way to school, it got out of a garden across the street and ran at us barking. It stopped about 3ft from us and continued to bark, little CRX was pushed behind me immediately. But the owner just stood and watched, halfheartedly calling the dog but not coming out as she was in her dressing gown.
The dog eventually ran away but not before the woman told me to "grab it"
erm no i am not going to grab some random dog, i would also never expect my child to. You never know what some dogs could do.
