My dog's nipples are enlarged, but she's not pregnant. What's wrong?

Hello. This is nothing to be overly concerned about. Manakoa is old enough that there are hormones circulating & this nipple just seems to be a little more sensitive to the effects of estrogen at this point in time. If you were planning on spaying her, this is a good time to consider doing so, but otherwise, as long as the nipple does not continue to show further hormonal influence, it should not significantly affect her. If it does continue to enlarge & seems to bother her, do see your vet. Thanks for contacting Petco Pet Education Center, formerly Petcoach.

Hello. This is probably benign mammary hyperplasia, but you do want to have this looked at, especially if she has been spayed. If she has not been spayed & has never been with a male dog, then this could be related to a false pregnancy. Also, has she been in contact with anyone who is on hormone replacement therapy? Sometimes, this can rub off on a pet & cause mammary enlargement. If no outside cause can be found, then have her spayed if that has not already been done, & submit a biopsy to see exactly what is going on with the tissue.

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.

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Princess. I would advise taking Princess to your veterinarian. It's possible that she is going through a false pregnancy (pseudopregnancy) if you are sure that she didn't get bred by a male dog. Dogs often get mammary enlargement and will lactate when they are in a false pregnancy. Your veterinarian can gather a history and assess Princess. They may want to x-ray or ultrasound her to confirm that she is pregnant or not if she was out of your sight within the past 2 months or so. A false pregnancy usually resolves without treatment but it's also possible that she is developing some mild mastitis from the mammary enlargement. Your vet can advise you on any treatment that might be needed. Good luck with Princess

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Is she was allowed access to intact male dogs she could be pregnant but you wouldn't see symptoms this soon. She may be experiencing a false pregnancy this is a hormonal imbalance where the body makes hormones that mimic pregnancy. The dog will nest, act anxious, carry stuffed animals around, the mammary glands can become enlarged and they can even produce milk. It lasts a few weeks then resolves. The only thing that doesn't fit is the excessive licking. Possible causes for excessive licking of the vulva is a urinary tract infection, crystals in the urine or a skin infection around the vulva. I would collect a urine sample and bring it with you to have Milah examined. I wish you the best!

[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.

Thanks for using Petco Pet Education Center, formerly Petcoach! Her nipples look normal at least in this picture. I would not worry about it as long as they do not look abnormal or irritated which does not appear to be the case. Good luck and have a good day!
