My dog is 61 days today last night her temp was 37.2 this morning was 37.1 is this a drop? Also last night she was clingy to my boyfriend and was nesting also breathing fast and not going out for a wee she is still eating ect I thought it might of been last night but no pups yet is she in first stages or am I just thinking this as she’s so close

Shes not to close they can go anytime from 59 days safely but doesn't seem like a drop to me. Temperature doesn't always drop either though so keep a close eye and good luck

She is 61 days just done her temp again it was 38.1.. she still scoffs food ect she just keeps lying around all the time
With her last litter last year she didn’t show any signs of labour I turned round and there was a pup so I don’t know what I’m looking for with her

Normal temp is 100.5F to 102.5F.  Most bitches in their last few weeks have temps around 100F but fluctuations from 99.5F to 100.5F are normal.  Temps will often be higher in the AM and drop as day goes on.  You are looking for a large temperature drop that persists at least 8hrs - this will be 24-36hrs prior to whelping.  So - 2 consecutive readings with temp 99F or lower.  Some will go as low as 97F.  You will need to convert to C if you use that.
