Why is my Great Dane having false pregnancies after breeding?

Updated On September 23rd, 2025

Pet's info: Dog | Great Dane | Female | unspayed | 5 years old | 150 lbs

Our Dane has had one litter before we got her. We bred her back in May and it ended up in a false pregnancy. We tried again at the beginning of November. Once again, another false pregnancy. I emailed the people we got her from and they said it's the male we are using. The male we are using is a proven stud. His breeder uses him all the time. What could be wrong with her?

There are many things that could be going wrong. She could have some kind of infection or an anatomic problem. She is also a bit on the older side especially for her breed. Even though the stud has aired puppies in the past his sperm quality may not be as good for various reasons. I’d recommend seeing a vet to start - your best bet would be to find someone who is particularly interested in reproduction in your area. They would probably recommend blood work after an exam and might recommend some infectious disease testing. When she is ready to go into heat they might recommend hormone testing to help determine the ideal time to breed.
