My male is a MOMMA'S BOY to the extreme. If I make a sudden stop, his little face hits the back of my ankle. Seriously. If I go to pee and I take too long, he'll jump in my lap. I love it, though. Now I had a female pound puppy until recently, and she was the same way. I think it depends more on who spends the most time with them. I'm getting a little girl in January, and I sorta hope she bonds with my hubby. I think he's adorable going around with a little fur butt in his arms.
