Maggie is very cute! D: I agree, that this lady sounds like a complete breed snob. I hate that. I mean, Petsmart is not a freaking dog show, and she is not a judge.
A lot of people have made snide comments about Gonzo. They have called him a "funny-looking Border Collie", and a mix (some people have actually guess Pit mix... WHAT?!), and "unique" in a sarcastic tone. Usually, they are the ones carrying around a trembling, undersized Yorkie or a "Poo". There have also been people have who stopped me to ask what breeder I got him from, because they were looking for a working BC and liked his type! The thing is, different people have different opinions - but I think it is just stupid and rude to make hurtful comments about a dog's appearance.
Personally, I call almost anyone's dog cute. Almost every dog IS cute, just in different ways.
