Some dogs may very well prefer to be under the blanket. Our little min-pin burrows under the blankets to sleep even when it's 90F, and he's one smart little dog -- and definitely has that selective hearing business! He knows good things come in rattling packages Even if he doesn't get any.
I have a book with several IQ tests for dogs, all very interesting. I think it's a great idea to keep them sharp and problem solving.
I am not to sure about the how bright my little dog is. She heard some dog on tv barking and ran to the window barking to see who was barking. The fact the window was closed and she bounced off made it even funny. I almost fell off the couch.
I think I need to get the book about IQ tests for dogs to see how mine rate and ways to help sharpen their IQ skills.
