Cold mornings and short does not make my Fur Children happy... Blankets helped, but not enough.. Anyway, THEY (3 of them) DON'T WANT TO SNUGGLE UP TOGETHER. So I have ONE PAD for each Dog House, Propped up right, leaning against a side wall, so each Fur Kid can lay against it and STILL HAVE A THICK BLANKET TO LAY ON.. It took bribery to have them lean against the pad (for introductions)... Now that they have figured it out they are happier....NOW when they HAVE TO GO BARK AT SOMETHING they have a warmer spot to come back to. I leave these on 24/7 since I work and the AUTO SHUT OFF TEMP PLUGS I HAVE INVESTIGATED, DON'T have the Temperature range I want OR are NOT TO BE USED OUTSIDE (under a porch and FOG - So A LITTLE DRIPPY at times)... 2 of MY KIDS have SHORT HAIR, they use this the most....
