[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.

    It could be that Sasha is experiencing another false pregnancy. It could also be that she is pregnant if she has been around an entire male dog. I would have her seen by a vet today or tomorrow to confirm that she is having another false pregnancy or if she is pregnant. Should she be experiencing another false pregnancy, I would recommend having her spayed. It seems to be a continual problem with her, and spaying her would prevent them from happening again. In addition, it would eliminate the possibility of her developing a pyometra, which is a life threatening infection of the uterus. You can speak to your vet about having her spayed.

    Hi and thanks for your request bout Bonnie's problem. These signs are typical of phantom pregnancy especially considering lack of mating, presence of enlarged nipples secreting milk (you are right about the milk production just before birth). False pregnancy, or pseudopregnancy, is a term used to denote a common condition in a non-pregnant female dog that is showing symptoms of 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. 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 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. Blood stained mucous is slightly more concerning though as there may be a uterine infection going on combined with the false pregnancy. In this case I would recommend a check up in this case.
