Breeding my female pug w/ Male Boston Terrier

Question
We have a year old pug female who we were not expecting to breed yet, but she went into heat and my Boston terrier managed to clear my deck and get to her. She has been acting very funny and seems to be more affectionate, I wanted to know first of all when should I take her to the vet? and How long is there gestation? Is it possible that she might not be pregnant? I would like to have waited until she was at least two will she have problems since she is so young? Also, My Boston has a condition were one of his scrotum did not drop so I don't know if that would effect him being able to conceive?

Answer
Hi Tiffany. Canine gestation is 9 weeks, or 63 days. A pregnancy can safely go between days 58-65. Unless she is showing signs of illness or a nasty discharge, there's no real reason to take her to the vet yet. You can take her in on day 28 or later to see if the vet can feel a puppy, you can also have x-rays done after day 50 to see if she is for sure pregnant and about how many to expect. There's a good possibility that she is pregnant, there's also a good one that she's not. It's really untelling in dogs, you can never be 100% for sure until the dog is actually whelping. Dogs also experience a false pregnancy, making their owner believe that they are indeed pregnant. I worry about her age, she really is young right now. Work with your vet, if she has any health issues that need to be taken care of find out now. At the first sign of trouble, take her to the vet. Make sure she gets plenty of exercise, and don't let her get fat. During whelping, watch for inertia (labor stopping), c-sections may be normal in your breed. From what I understand, the Pug needs help to cut the cord and open the sacs. Make sure you know how to do that. As for your boy, if he has an undecended testicle, then he really needs to be neutered. That testicle that is still inside of his body may be more prone to cancer. Also, this condition can be hereditary, so you also don't want him to pass it on to his pups. A dog with one decended testicle can, in fact, sire puppies. If I can help with anything else, let me know.
