That my dogs are flaming homosexuals! The Chihuahua runs up to my Pug who is lying down, of course perfect position, so that the Pug can now "clean" his wiener. And of course he helps the Pug by shifting positions and lifting his legs so that he can get a better angle at "things". (Funny side note though, always cracks me up when the wife is home at night and talks about the Pug having bad breath, I silently giggle)
And they do this ALL THE TIME. And don't even get me started with how often they sniff each others butts. It's absolutely hilarious to see the Chihuahua trying to mount the Pug from behind, being even smaller himself, and then the Pug drags him around the house as if he's not even back there.
Filthy abnormal pigs!!
