I have bought 2 heat pads one a Warwick and one that looks like it's come from China. I have tried them both out and expected them to be a similar heat to an electric blanket - both just feel very slightly warm, sort of like a tepid hot water bottle - is this right?

I borrowed one from a friend and just like you it was luke warm but if you keep your hand on it long enough it will feel warmer. She's used hers for years and I didn't have any issues with it, worked well.

Thanks - thought they must be ok with both being same temp - just don't feel warm enough to warm puppies. Mind if I have a hot water bottle I like it to be really hot!!!

If puppies (newborns) get too HOT, they are miserable!  I've overdone it on occasion and was amazed!  So luke warm is probably spot on.

> just don't feel warm enough to warm puppies

the correct temperature is reached according to the weight of pups.

I have always used Petnap, wouldn't touch anything else.
