re: Thoughts on people that bring their dog to a stranger’s house?

We had someone bring their dog and they tied him to a tree in the backyard. Unbeknownst to us there was a hornets nest under the tree. After a while the dog started yelping like crazy and was being swarmed by the hornets. The owner had to run out there and untie the dog while getting stung by about a dozen hornets. That didn't look fun. Next time the dog stayed home.
