Why are my dog's nipples enlarged and producing milk after heat?

She may be having a false pregnancy. If she had contact with a male while she was in heat, she could be pregnant. She could also have a hormonal problem or a mammary tumor. It would be best to take her to a veterinarian for an exam. The vet can also tell you whether she is pregnant. Unfortunately this is impossible without a hands-on exam.

Hello and welcome to Petco Pet Education Center, formerly Petcoach. It is possible that Harley could be going through something called 'pseudo-pregnancy'. Dogs can develop mammary glands, produce milk, and will sometimes even start to nest and collect small stuffed animals to nurse. This is normal and will subside in a few weeks. However, it is recommended to get her spayed before her next heat so she doesn't have to go through that stress again. The other possible cause is something called a pyometra. This is an infected uterus and is life-threatening. If you notice any discharge from her vulva, if she is weak, not eating, drinking more, or acting abnormally at all, I would have her seen by your vet right away. Best of luck with Harley.

The timing and symptoms could point to a false pregnancy. Have a examined by your veterinarian for confirmation. Treatment is typically not required in mild cases. Symptoms should abate within 2-3 weeks. If they don't or her behavior worsens, your vet can dispense medications to decrease milk production and possibly tranquilizers/sedatives for anxiety. Severe cases can be treated with hormone replacement therapy. To prevent​ future episodes, having her spayed would be the recommended course of action.

[False pregnancy](https://www.petcoach.co/article/false-pregnancy-in-dogs), or pseudopregnancy, is a term used to describe a common condition in a non-pregnant female dog that is showing symptoms of [pregnancy](https://www.petcoach.co/dog/condition/pregnancy/), lactation, or nursing, without producing puppies. The affected female dog shows these symptoms about a month or two after her estrus (heat) is over. A hormonal imbalance is thought to play a central role in affected female dogs. Depending on the severity of problem, the symptoms may last for more than a month. Unless symptoms persist, treatment is typically unnecessary. Otherwise, your veterinarian may recommend hormonal supplementation or spaying to prevent further episodes. To reduce mammary gland secretions, your veterinarian will advise you on using cold or warm packs to minimize the stimulation that promotes lactation. An Elizabethan collar (cone) can also help prevent the self-nursing or licking behavior that can stimulate lactation. In some patients, reducing the daily food intake can help to reduce the production of milk. If you are not planning to breed your dog and do not want her to reproduce in the future, [spaying](https://www.petcoach.co/article/5-great-reasons-to-spay-or-neuter-your-pet) is recommended for preventing future episodes of false pregnancy behavior. The overall prognosis is good and most dogs improve within two to three weeks, even without treatment.

Hello. If you are sure that she is not pregnant, then this is just a hormonal response. The breast gland tissue may regress a bit, but as long as she remains unsprayed, she may develop a little more with each heat cycle. Spaying her now may help regress the tissues totally, but with each additional heat cycle, she may develop just a little bit more. So yes, this is a normal condition in an unsprayed female dog. Thanks for using Petco Pet Education Center, formerly Petcoach.

It is not unusual for the vulva to remain swollen for a period of time after the "heat" cycle is over. In dogs, there are [4 stages of estrus](https://www.petcoach.co/article/anatomy-and-function-of-the-reproductive-system-in-dogs). The combination of proestrus and estrus, which is often referred to as "heat" by breeders, lasts approximately 21 days. "Heat" is followed by diestrus and anestrus. During proestrus, the vulva swells and has a bloody discharge. During estrus, the vulva softens and becomes pliable in preparation for mating. It can take several weeks following estrus for the vulva to shrink back down in size, but it will never go back to the size it was before the first heat cycle. The same is true of the mammary glands, which enlarge slightly in preparation for [pregnancy](https://www.petcoach.co/dog/condition/pregnancy/).

That could be a normal reaction of the mammary glands after the season, and it is likely to resolve spontaneously one or two weeks after the season. if signs persist more than that and discharge comes out from nipples a check up would ideal as false pregnancy or mammary gland inflammation/infection may be present.
