Many reasons
I have known 2 dogs (not my own) that are small, that I've liked. Ever.
I don't like small dogs in
general cause of their owners. I don't like the materialistic way people carry them around like an accessory. As if the dog is an object. And I especially don't like that they nip and bark for no reason.
If you're gonna get a dog, train the dog.
When I see a dog with bad manners, it just reminds me how lazy and stupid people actually are.
I also have been bitten by small dogs, cause they're nervous. I find nervousness in a dog to be annoying.
That is what Cesar teaches btws....that they're nervous...and he's right. They bark out of fear.
What ever that guy did to your pup in the OP...he did it wrong. Dogs have a different mentality then us, and they have a hierarchy that you need to understand before you get a dog....or the dog will growl at you if you're by their food, they will growl at you if you don't give them their toy, and they wont respect you.
So really...it's the lack of respect that I see that the dog doesn't have. And it's because someone thought it was cute, and didn't think about the dog's happiness or the surrounding people.
Also I go to the park with my dog and every SINGLE TIME, all the little ass dogs...hump my dog.
If they have been domesticated properly then I have no problem with any dog. If they haven't then I don't hate the dog...the dog is innocent, I hate the owner.
And it is hate.
Yea, I mean I don't know about all the controversy. I have no idea what the guy does off the camera. But I don't think people understand his intent. The way it comes across to me when he's talking, it sounds more like he's getting into the dog's mentality and trying to get to the root of the problem. Where people are just trying to find a quick fix....which doesn't work. Just my opinion though.
