Listen, dogs are great. A lot of people love them, and as an owner you have a responsibility to keep them entertained and not just locked up in the house all the time. However, you aren't entitled to bring your furry friend anywhere and everywhere you see fit (unless they're some kind of service animal). The truth is, not everybody is as comfortable with canine companionship as others. Also, there are a lot of pets out there that are not as well trained as they should be.
Still, this doesn't stop some dog owners from believing that they can bring their pet wherever they want. This is something that u/TheCornStarMum recently had to deal with, when a friend brought along their dog to a garden party she was hosting after she specifically told them not to. To make things worse, the animal was left unsupervised and ended up digging up and eating different crops that were in the garden.
This ended up making the dog extremely ill, prompting the owner to blame party's host for their own inconsiderate behavior. It's no shock that Redditors took the side of the person who just wanted to make sure that their cats weren't going to be uncomfortable.
