Princess Zoe, yes its just like that, same idea! But Im looking for a soft fleece cover (like they use for blankets and doggie jackets), instead of sherpa!
I think the doggies like it so much because it pretty much fits to their shape, so they can lay on their back supported on both sides, which keeps them warm
Can you believe I have a 3 feet wide bed for my 10lbs Yorkie? Soo spoiled lol, atleast it has room for her toys hehe
