answer:I have owned many dogs and yes they love to have their back scratched. if you think about it, this is the only location that a dog cannot scratch and they welcome it. my border collie is a classic example. when i scratch his back he either: 1. freezes in one location for the scratching to continue or 2. he submits all and collapses on the floor begging for more. Its perfectly normal for a dog to want its back scratched. i am no dog, but i enjoy a back scratch, just like Mikey my border collie. and no, Mikey did not tell me this.
