Great Dane pregnant by smaller male dog: Will birth be complicated?

Hello, I’m not sure if there was supposed to be a photograph of the male dog attached to this post or not. If you have a large male who breeds with a small female, there is always a concern that she will not be able to have the puppies and will need a C-section. Any small female dog who is having puppies should have radiographs done after day 45 to see how many babies are expected. If you do not want her to have a litter, I recommend calling the veterinarian and discussing getting her spayed ASAP. Some dogs can have a shot to stop the pregnancy but there can be some serious side effects to that. Getting her spayed will eliminate an accidental pregnancy in the future. Getting her spayed also has other health benefits and is recommended for any dog not intended for breeding. I hope this helps and please feel free to post any additional questions!

No this isn’t entirely correct. She does however have a greater chance of needing a C-section if the puppies end up being bigger than her birth canal. Which is why it’s best to have her examined by your vet and radiographs taken to look at the size of the fetuses. If they are too big to pass, then a simple C-section can be scheduled for the Mama dog. I hope this helps. Best wishes and take care.

Thanks for the question. Interbreeding of a mother to an offspring does carry a high risk of genetic problems. It is possible that the pups will have problems, or that they will be born normal. Since she appears to be far along in her pregnancy, I wouldn't advise terminating the pregnancy at this point. I hope all goes well, and I recommend spaying/neutering, or keeping offspring separated once they are over 5 months of age to prevent future pregnancies.

It is likely they will be fine. As long as the parents are close in weight (within 10-15 lbs or so, the puppies should be fine. However just make sure to get radiographs when Pixie is beyond 45 days gestation to ensure the feti are not too big to go through the birth canal. I hope everything works out well for your pet Pixie. Best wishes and take care.

There are probably close enough in size to not have any issues, but it is difficult to say with any certainty. Being mixed breeds, it is possible there may be some possibility that the pups could be larger than the mother. If you choose to proceed, after vet checks of both dogs, have the mother x-rayed about a week before her due date. Your veterinarian should be able to determine litter number and size then may predict more accurately if surgical intervention will be necessary.

Hi, thabks for using Petco Pet Education Center, formerly Petcoach! The size difference may or may not be a problem. If her litter is large the puppies will be smaller. If she only has one or two she’d be at more risk for needing a c-section. I would have your Vet take an X-ray at day 50 to confirm pregnancy and to count puppies. Write down the date she was bred. Dogs are pregnant 60-63 days. Starting at day 55 start taking her temperature daily rectally. Stage 1 labor tends to start 24 hrs once the temperature drops below 99 F. But your Vet can help you and go over concerns once we know she is pregnant and size of the litter. I hope this helps and good luck!

I would strongly suggest to keep her monitored during pregnancy as c-section may be needed to deliver the puppies. Radiographs at 40 days of pregnancy will be very useful to assess the size of the puppies and make sure they can be naturally delivered.
