So we went to the dog park today and my dog was trying to drink water with another dog the owner got mad and called my dog a name and told her to get away I tried to grab my dog and they both started barking at each other as my boyfriend was trying to get our dog the man proceeded to take out a baton and strike my dog my dog has a fuckin welt on her back and the back of her leg is bleeding so I confronted him and then another man wanted to join in and they ganged up on me saying my dog was the aggressor my dog doesn’t bite anyone she barely barks so you beat my dog all because you didn’t want your dog sharing water with mine then had the nerve to tell us we need to leave .

EDIT:

I was like if YOUR Dog was trained you wouldn’t have to bring a freaking baton to beat a dog he’s like no I bring a baton to beat other dogs that are aggressive towards mine
