My dog was spayed, but an ovary was left. Does she need more surgery?

OVH is the most common method of spaying a female dog that most veterinarians will perform. Ovariectomy (OVE) is when just the ovaries are removed. A newer trend that is still being researched on its effects on dogs is the removal of the uterus but leaving the ovaries. The dog will still have heat cycles but is unable to become pregnant. Traditional research has suggested that after going through several heat cycles, dogs are at risk for developing mammary cancer. Until that research is proven wrong otherwise, removing the hormonal influence that the ovaries have on the body helps reduce the risk of mammary cancer according to current research. Spay techniques are surgeon preference, so if your veterinarian would like to leave the ovaries in and remove the uterus, I would discuss this further with him and ask him about the pros and cons of doing such a procedure. Does he know if the risk of mammary cancer is altered in doing this procedure differently? Removing the uterus does not cause any major complications other than urinary incontinence, which does not happen in all spayed female dogs but a good majority do suffer from urinary incontinence due to being spayed. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Yes, this will be due to the ovary left behind. Because this ovary is still there, it's releases hormones and causing Kitty to have symptoms of heat. Yes, surgery is recommended to find that ovary and remove it.

I do recommend taking Aarfaa back to where she was spayed to have he remnant removed surgically. This is best performed when she is displaying signs of heat/ season - eg when she has a swollen vulva and or discharge. If it is left she will typically have heat cycles and be attractive to male dogs which can be a nuisance. Potentially she could develop an estrogen linked infection of the stump where here cervix was - this is called a stump pyometra. I understand your concern for putting her through surgery again, but in the long term it will be better for her.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Trixie. I agree, this does not sound right. It sounds like she is showing heat behaviors, and this can be a sign of an ovarian remnant left behind. I'd have her seen by a vet today or tomorrow for a hormone stimulation test. This will diagnose if she does have an ovarian remnant or not. If she does, she will need surgery to remove it. Best of luck.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! If your Vet only removed the ovaries then she still has a uterus and that is where the blood comes from. After this heat she will no longer have them because the ovaries are gone and they provide the hormonal influence. If an intact male dog mated with her after the surgery I do not think she will get pregnant as the ovary makes the eggs. I hope this helps!

Hi there! ORS, or ovarian remnant syndrome, will likely cause little issue for your dog health wise. You may notice heatlike symptoms with her from time to time (blood spotting, swollen vulva, etc). She may attract males but cannot get pregnant if her uterus was removed. That said, if she is still producing estrogens you have a small chance at her still getting mammary tumors since all of the tissue producing hormones was not removed. I hope this helps!

Thank you contacting Pet Coach about Sophie! An ovariohysterectomy means her uterus, both ovaries, and uterine horns were removed. Veterinarians are able to perform spays using much smaller incisions, which is why hers is so small. You don't need a large incision to spay a dog. Each dog reacts differently to the procedure, and some are more active than others. It's very important that you keep her as quiet as possible to ensure correct healing and avoid post-surgical complications like wound breakdown or a sermoa. Best of luck, I hope this helps!
