Sizmic, thanks to you, I have been treating her. I could not find a vet to help. I have used tribrissen (smz/tmp) and oxytet, but am not sure if I treated her long enough. I also vaccinate her with Neoguard at standing heat. And would have vaccinated her though out pregnancy, but she came back into heat twice, but didn't take.
She stood on Oct 10th, she cycles every twenty one days like clockwork. I have not given up.
