I have bred my female. This is her third litter. The last two without problem from start to finish.
Now on day 17 after breeding she starts to bleed. I take her to the vet and they run a culture and put her on anti biotics. It stops. Everything is ok. Today day 22 the bleeding has started again.
More antibiotics. The culture results say only a slight vaginal infection.
Is she loosing her pups?
Its not pyrometria.

I would be getting an ultrasound about now, and consulting with a repro vet.

Could this be a split heat cycle and she's not pregnant?

She had her regular full heat cycle. I am due for an ultra sound in one week, so will see if we have pups or not. Its really very strange
