I've had two female dogs, current one is a Lab Aussie mix, and strangely, we don't necessarily "scratch" instead mostly pet the belly.
I've always went with the submission route, because yes, canines tend to HATE being on their back with their underbelly exposed, and non-domesticated canines really don't do it unless showing submission to the alpha male or female. I'd say it seems to be more females submitting to alpha female, because male dogs tend to despise the concept of submitting to other males.
But, our little female aussie is strange. She shows submission, but I think she's mostly screwing with out minds or using it to gain more attention. She's an attention whore, and is our shadow to the extreme, very attached to us. However, she also loves humping, and she's been spayed. I'm pretty sure she wants to be an alpha, and at times we probably give her mixed signals into thinking that's alright.
