Have you ever seen the sweatshirt on www.cafepress.com?

It says on the front....YES THEY ARE PIT BULLS.

And on the back it says....YES THEY ARE FRIENDLY.

I thought of your post when I saw it.

Sorry you're having a problem with people assuming your dogs are killers. It's a shame. Just ignore them. As long as you and you're dog are happy and having fun on your walks, who cares what uneducated people think?

Take care!
