I'm thinking at this point there could be 6 to 8 baby bassets.There are two horns of a dogs uterus that the eggs attatch to ,so generally, if say three are seen on an x-ray then there could be six. I have not had her x-rayed and as long as normal stays normal she will not need to be, but once she is done whelping the puppies I may have the vet x-ray her then to be positive they are all out,along with a shot of oxytocin. She is a long girl and could have one or two up under her rib cage. Which would then add up to ten(OMG). She will be in first stage labor when her temperature falls below 99.9 she will shiver as if she is cold, she will start to nest(she'll have the erge to dig) then pups are usually expected about 24 hours later. 2nd stage is when the contractions start and she gets serious about, "Push em' Out, Shove em Out,RAH,RAH,RAH."
