Mine take it anyway they can get it. They loe the belly rubs although Beau does go inot kickstart mode pretty easy. What really gets me is when brushing Beau and Stella sometimes too with this brush that is like a saw blade with a handle. I foget the name of it, but you dag it against the hair to minimize shedding. Beau will get into it so much he falls sometimes if you scratch his back with it long enough.
As far as the other forms of attention, say a belly rub he usually starts to give a little growl if you quit too soon, or he'll start nudging and talking if he doesn't get what he deems suffiucient.
The reason I say they take it as they can get it is because when you pet one, then there comes a jealous pup wanting their fair share, then another, and just recntly my last rescue has lightend up and is getting in on it too. 2 can be overwheliming, much less 4. Its almost like when you happen to catch one of them by themselves you kind of sneek some rubbing and petting, but silly dogs they always give themselves away, and then the others are a comin.
