Hi all, my girl is 58/59 days pregnant and I am a bit worried.My vet says that he thinks she is having only one pup.She is a small dog (chihuahua) but the vet also said he does not feel that the pup is too large for her to deliver (of course no one really knows until the birth).I have been reading some older posts and read that sometimes only one pup will not produce enough hormone for the bitch to go into labor and this worries me.Has any one out there experienced a similar situation and if so can you give me any advice?Thanks Melanie
