I put yes but, Brutus does not scratch, he licks the couch uncontrollably right before he goes to sleep. This is how we know he is ready for night night. Frankie doesn't do anything but plop down in his crate. We tried to let him sleep on the couch with Brutus but he slept for about 30 mins and then stood in the kitchen barking and causing a rukus because he couldn't figure out where everyone went. lol
We've had 2 boys and 2 girls. The boys were the ones who nested, which I always thought was funny - you'd think that the girls would be the ones to nest.
Nope. Our girls did though. Charley does prefer to go to sleep on a blanket under the comforter rather than on top of the top sheet I put over the comforter to keep it clean.
I laughed when Tallulah first did this! I've never had a dog that move her bed around before. She also scratches at it for a while or if I give her a blanket on the floor she does the same thing. She does it a bit at the blanket on the sofa, but I discourage that because that blanket is there for the sofa not for her.
