Chester our 10 week old GD.. Couldn't settle on the carpet we had in our rec room. he would try one position then another but just wasn't happy. He would flop out Bear rug style on our laminate flooring- or the ceramic tile by our front door.
It has been pretty warm here lately and I know this floor is cooler for him. It broke our hearts to not have him comfy in our most comfy room..so DH built him a mini ceramic floor to sleep on in the rec room.. He loves it. He will now spend lots of time down there- it is cooler in the basement anyway.
Next stop.. pull up all the carpet in the house?? :)
