We had a dachshund who had a lot of false pregnancies. But she had 2 litters before doing that. One litter at the breeder who sold her because the puppies were too small (this was a show breeder and the dog was a champion) and another litter after we bought her and she got herself pregnant with a dog almost 3 times her size. It was hard to see that she was in heat, you never saw any blood, she was licking herself clean. She had 7 puppies and they were not small. We were lucky she did not need a cesarean section and the delivery went just fine. We had her spayed at 10 years of age after finally a vet told us that the only way to stop that was to spay her.
So, Jodi, I can only recommend to you that you have her spayed because she could have a false pregnancy every year.
Jodi (FannyMay), why would it breake your heart ? They give them pills or shots and the milk goes down and it's over. And it's like nothing happened. That dachshund reached the old age of almost 17. And she ate nothing else then people food. And besides those false pregnancies never needed a vet. But that was years ago.
