my chihuahua had his first oprgasm-damn the boys hung (naturally, since he's sorta related to me) anyway, he has a big stuffed barbell -bout his size-that he humps-keeps him off my arm-and usually he loses interest before his sword comes out of his sheath-but t'other day he kept it up, and next thing i know, there it is all pink and proud-and he got kinda a glazed look on his face...just 5 months old, so no mess-but he loves that barbell now...being a pet owner surely is educational
My retriever (RIP) used to hump this one pillow we had. He was fixed too. I guess they never lose that urge entirely. He used to squat when he pee.
