I hate dog people. Not people who own dogs, but full-on dog people. The kind that take their stupid dog to the store.
Pet's Mart, ok, I get it, bring your dog. Home Depot? Nope. Grocery store? Nope. It's not a park. Leave them at home. They don't even have to come in the car with you.
It serves no purpose other than warning everybody that you are a moron.
