My beagle is due on Feb. 14 and I haven't been able to hear the puppies heart beats with my stethoscope. I know she had has one other litter and the puppies were all healthy. I skipped a heat and bred her again. On the day she was supposed to have her pups she didn't so I waited till the next day. She had one and it was dead. I took it for an autopsy and the vet said it suffocated. I guess she was holding it in too long or something. But she didn't show any signs of labor till the day she had it. I also was able to feel it moving and I thought there were more. B/c she was so big. This time I skipped a heat again and she doesn't look pregnant. I don't know what the problem could be. Do you all think she could have something. If she isn't I'm going to have her tested. My yorkies came into heat and it was their third time and the first time I bred them. They didn't have any pups on the day I thought they were. Do you all think my stud was just too young? The girls are 3 and he was 10 months. He didn't tie with the first but he did get good action. My second did tie and it was like her 14 th day. No pups for them either. BTW my Beagle is 4. This will be her last litter if there are no pups. My Yorkies I will have to see in a while.
