When is the best time to *attempt* to palpate a pregnant bitch. I've never been good at it, no matter how far along they are.
I know if you try too soon, it's difficult, and then if you wait too late, it can be difficult.
The best days to palpate are from day 28 to day 35 of pregnancy. I have palpated at day 26 and felt them. Lumps will fill like grapes at that time, then bigger grapes.
After day 35 the sacs are filled up so much it is hard to tell the difference between babies and intestines. Easiest to do on thinner girls.
