Online vet, Dr. Marie

Dr. Marie replied:

Hi and thanks for your question.

It is definitely not normal to have a heat cycle that lasts longer than 3-6 weeks. There are a few possible reasons why this may be happening to Dixie.

It is possible that she has either an ovarian cyst or ovarian cancer. In either case, the treatment would be to have her spayed.

It is also possible that she has some infection in her vagina or uterus. However, this usually doesn't cause her to still be attractive to males and want to mate so this is less likely.

I would highly advise having your vet examine her. They will do an inexpensive test where they will swab her vagina and determine if she is in heat or if there is infection present and then they can advise you from there. Most likely though it sounds like she will need to be spayed. If your vet is suspicious of a tumor then they will send the tumor away to find out how worried we need to be.

I hope everything is ok!

Dr. Marie.
