The bitch i am hoping to get a puppy from is definately pregnant,well its looking like she is although hasnt been scanned.however she is very small,only showing slightly around the tummy and apparently only when she lies down on her side is it slightly visible.im hoping for a pup to show and theres one in front of me to choose.An average for this breed is around 6 puppies,do you normally have have an idea of litter size at this time?

Not in my breed, unless you know the bitch well you would hardily notice she was pregnant.

I would have no idea whatsoever after just 6 weeks!

Too early for you to tell.
