Let me tell you what my 2 indoor dogs think!  They love it.  I bought 2 in different sizes, but the dogs keep trading out beds every few hours! It's hilarious to watch the bigger dog  squirm and snuggle into the smaller size bed and the little bitty dog hide himself in the bigger bed; then  it reverses and no one is growling or fighting, they seem to enjoy themselves, so we just let it be. Worth every dime!
