Try standing on it! The heat pad is only hot when something is on it..if you get my drift! I only use a pad, in my large breed Mum is generaly too hot anyway and with a pad she can avoid the hottest part of the box. I find to place it in the middle is good as Mum always goes in and lies along one egde or another but the puppies lie in the middle and suckle so they are always on the warm bit?
I agree with the statement that too much heat makes for poor mothering, I keep my lounge at a contant 72 degrees night and day for the first 2 weeks then gradually cool it down, now at 4 weeks my pups have no heat at all and still spread themselves out to stay cool. I do have a large heavy coated breed though so not nesesarily the right thing for smaller shorter coated breeds. Don't be tempted to Overheat though, If pups gather in a heap they may need a little more but if they spread out they are just right. And if Mum is comfortable she will spend more time in the box thereby reducing the need for too much extra heat.
