Do Dogs Hibernate?

My poor Hans has probably had about five walks in the last two months. He gets to go about two blocks once a day. Yesterday I ventured to walk them a little further and went 1.66 miles and paid for it this morning with an achy foot. So, in answer to the question, "Do Dog's hibernate?", I give a resounding, "YES!". Well, at least, yes if you buy them a new bed from COSTCO (seriously this one is like the Mercedes of doggy beds) and you don't exercise them at all! My dog is becoming a complete lush. The pictures will prove everything. All of them were taken at different times and on different days, with the result being the same...
