It's either the real deal OR she's having a false pregnancy. The only thing you can really do is take into account the date(s) that your friend took your girl out and this could've happened because he seems like the only likely candidate and start keeping count of days from there!
And then when it's time, do an ultrasound or x-ray to see what's in the uterus.
Until then, there's not much you can do. You can ask your vet to abort the pregnancy; you can do an emergency spay (costly and not worth the risks imo) OR you can wait it out like I mentioned above and see if anything pops up on the screen at the time of the ultrasound or x-ray.
Good luck to you! Keep us posted- |
