Wow thanks for all of the replies. I quickly decided not to adopt that dog after reading things here and on other forums. Plus the dog apparently didn't do well with its cat test they did. They didn't tell me, but I did check back to the petfinder listing the other day, and I noticed an extra line in the middle that says "He is not good with cats." They threw it in there at some point in the past week.

The person who personally rescued and helped us adopt our dog Petey told me that she had a wonderful AmStaff that ignored cats, was good with other dogs if properly introduced, and was very friendly. Friday I took Petey to meet this dog, and it showed no interest in people at all. It was too rough with Petey at first, but after Petey had about 15 minutes, he went back to her and they played all night. Unfortunately I don't think I want a dog that

a) has to be muzzled in my city
b) can't ever EVER go to the dog park
c) wouldn't really trust around my cats
d) wouldn't trust to play with Petey for even 30 seconds unsupervised
e) shows no interest in affection or attention from people

I'm definitely sticking with the boxer rescue group. Someone should be contacting me this week, and hopefully I can finally find the right dog. It actually took me until today to realize I don't want the AmStaff because it obviously isn't a good match. Is it obvious that I want to save every rescue dog? haha. Thanks for the replies though.
