What is one (two, or a few) thing about other dog owners that makes you cringe?

All my pet peeves come down to a single unifying word, IGNORANCE.
Whether it's feeding habits, training, health care, grooming, breeding, or just plain prejudice. All the problems I have with other pet owners and non owners comes down to ignorance.
My biggest pet peeve right now is prejudice though. You see I own 2 American Pit Bull Terriers. And I have been yelled at and berated and condemned because I am also the mother of 4 children ages 7-16 one of which is disabled. This breed I have found is indeed a breed apart! It's drive to please it's owner is overwhelming. Unfortunately this is also the reason these dogs have such a bad reputation. Most owners either raised them to be this way or did not train them properly. Or bought their dog from breeders who have not bred out undesirable traits but actually encouraged the breeding of aggressive and nonstandard sizes in this breed.

My APBT Mathias in this video is breed standard, trained and all that is good in this great breed.
