The heating is on all the time but we dont have centeral heating.. we have eletric heaters so they generally keep the place warm but turn off and if i had a door open or similar we loose heat pretty fast.
her bedroom with the pups was always kept warm, i fiddled with the heater to mean that it never shut off.

shes her normal self in respect to does the doggy dance when you get in, dropping her ball on me as if she wants me to throw it for her. She seems to have totally forgotten the last week.
I am keeping her on the calcium supliments as he said even though she was "normal" she was at the lower end of normal, the help i gave her with milk, eggs, supliments may have just kept an edge off her and for the pups to not be suckling for 36 hours put her back in the normal ranges.
either way. this will never happen again. I just cant deal with this again.
