As some already know, I have an issue with butts. My roommate would use them as a measure of how cute a guy is, I would tell her gross you know what comes out of there.
Now Autumn is also like this. She gets defensive when other dogs sniff her from behind. She only greets dogs face to face. She doesn't sniff other dogs' poo. She has an area to go potty in outside and only crosses the invisible boundaries of that area to go potty. Then she makes a beeline out. Even if all the poo is cleaned up she wouldn't even go near the area to pick up a treat.
Do you think Autumn picked up her butt aversion from me?
