Having a large dog but not training it is crazy right?

Ok so in the building I live in almost everyone has a dog. And some of them are massive, ferocious beasts. Usually I’m chill with dogs but when an owner doesn’t train them, and they like jump all over me. It’s so annoying. And dangerous!

Has anyone had to deal with this before? Idk what to do when I’m in an elevator and these dogs get in. Ugh!
