The heat has been unbearable here as well. 100° ambient, with an index of 108° on several sequential days. I haven't been out in the Yard for over 10 minutes during the day, for the last month. Being real cool is not comfortable to me, we keep the house at about 76-78° and the bill is still extremely high. Now, here's the kicker...

I must have two of the most cold natured Yorke's ever !

Both of mine (when napping) will migrate to the most fluffy and convoluted arrangement of old Towels and Quilts that are available. AND, frequently through the day, will go outside (we have a Doggy Door) and lay face up directly in the Sun for as much as 10 to 15 minutes.
