Why is a ping pong ball-sized mass falling out of my unspayed dog?

No, this is not normal at all, and it will not go away. It sounds like Magic has a vaginal prolapse, and she has to see a vet for this immediately. It needs to be replaced into it's correct anatomical position, and given that it's been out of her vaginal for a month, it absolutely has to be corrected now. Please take Magic into an ER vet or find a vet on call to see her now.

It could be a vaginal prolase of a vaginal tumor. You should take Gracie to your vet right away as there are a number of concerns for these condition. First of all, some dogs may have problems to urinate, which is a serious emergency. Secondly, some dogs want to bite the protruding 'mass' and by doing that they will make it bleed and introduce infection. Vaginal prolapse is not always a surgical condition (it often responds to medical treatment) while vaginal tumor should be surgically removed.

This is called a "vaginal prolapse" and is common in young intact females. It usually happens right before or during the dog's heat cycle. This is a hormonal problem associated with an overabundance of estrogen and usually, spaying the dog will remedy this. It usually happens right before or during the dog's heat cycle.

This is a medical emergency, and Lola has to see a vet now. I would be concerned she has a pyometra, and that is fatal without treatment. Do not let her problems around other dogs prevent her from getting the help she needs, just her into a vet. You can keep her away from other dogs while waiting to see the vet, but given the situation, I suspect you will be taken in immediately for the vet. Please take her into a vet immediately.

This ball could be a vaginal prolapse, which does require immediate medical attention. When a tissue is displaced from it's correct anatomical position, it needs to be returned to it's correct place or else the tissues can become infected and/or die. I would take Angel into a vet right away. If paying for a vet is an issue, you can see if your vet accepts payment plans, if there is a low cost clinic in your area, or you can apply for Care Credit online. There is also an organization called Red Rover that give grants for treatment of sick animals, and you can see if you qualify for one of their grants. http://www.humanesociety.org/animals/resources/tips/trouble_affording_pet.html?credit=web_id91754962 https://www.redrover.org https://www.carecredit.com

This looks like a vaginal prolapse. That is when the vagina turns inside out. This is very swollen and needs to be lubricated and then manipulated back into place. You can clean it gently with a warm wet cloth, then apply KY Jelly to it or Vaseline to protect the sensitive skin from injury, then I'd bring her in tomorrow morning to get this examined and treated. I'm afraid if you leave this it may not get back to normal. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Piper.

If Molly is not spayed, I would have her examined by a vet ASAP. It is possible there are issues such as a urinary infection, pyometra (infection of the uterus), prolapse (if things are protruding) or even additional issues such as parasites trying to bury in the skin. Since there is also blood present, it'd be best to have her checked out. Other signs to look out for include lethargy, fever, changes in eating or drinking, additional discharge, increased urination, and cloudy/bloody urine.
