Is it weird I judged a guy by the breed of dog he has in his photos?

A guy reached out about volunteer work I inquired about and a walking partner in order to lose weight. I know he was probably interested in dating based on his profile...

First of all, don't get me wrong. I LOVE animals. I adore them. However, I do have 7 month old kittens and no dogs. He has a huge dog, much bigger than a German Shepard or something. I guess, it could be a Great Dane but i haven't seen it's body in order to tell. Of course, it's wearing one of the collars that I can't stand...

I do love all animals including dogs; however, I tend to believe certain types of personalities want huge, scary looking dogs. I think I'd date a man who owns small or medium sized dogs. Lol.

Is that weird? I used to be different when I was young and dumb, but I really do think it says something about the personality of the man (in most cases).
