I don't know why people dismiss it so much.
I have done the temp check with every litter. Different bitch each time and it has been 100% bang on everytime.
It happens for a reason. I think when people get it wrong they are not taking it enough and not and the same time each day and recording it properly.
I have my readings from my first litter still. My first litter arrived one week early , I was just about to nip to the shop when I thought I would take her temp first. Lucky I did , she had her first puppy a couple hours later.
It was one of the most useful peices of information I ever got .. funnily enough it was Val that gave me it :-)
