I feel your pain Dinah,....my best dog Belle had crazy heat cycles that were never on time, no telling when she would come in. I got tired of dealing with it and had both her and Abby spade. Good thing I did too, when I went to pick Belle up, my vet, who's a friend of mine, said it was a good thing I brought her in,.....she had a really bad case of endometriosis, so all is well that ends well I reckon.
Did they correct the problem? Ive never heard of dogs having endometriosis.
Yes, that did it. She's fine now and seems to feel better now that I look back. My wife said that she felt for her since she herself had it years ago. I'm not about to raise any puppies now, so there's no reason to not have mine spade. I'm ready to hunt and enjoy having 2 good dogs to hunt with. Good luck with your problem.
