So your pot-bellied pig is leaving foul-smelling, wet spots on your carpeting all the sudden. There is nothing to be alarmed about, and there is an easy solution: Get your pet neutered, or fixed. By the time your pig is two months old, you should make an appointment with an exotics pet veterinarian to have him neutered. Veterinarians recommend that you have your pot-bellied pig neutered no later than when he turns three months old.
Pot-bellied pigs become sexually mature and start humping, ejaculating, and emitting that foul odor at an early age. It's also important that you choose a vet who is familiar with pot-bellied pigs and that you not attempt to solve the problem yourself. Until your pet is fixed, you will have to contend with him turning aggressive and humping anything he can, including shoes, furniture, your legs, and even other pets.
How to Avoid and Clean the Discharge
Unfortunately, that nasty wet stuff you are cleaning up is most likely pig ejaculation, or semen, sometimes mixed with urine. When your pig gets sexually excited, his penis, which is shaped like a corkscrew, comes out of his prepuce and the pig ejaculates his semen.
Once the semen gets on fabric, you can remove it by blotting it with a paper towel or damp cloth. Then rub the affected area gently with a dishcloth that has been treated with laundry detergent. Blot the spots with a clean, dry cloth and repeat the process if necessary.
Stopping Sexual Behavior
Your pot-bellied pig will eventually stop ejaculating and humping once he is neutered. When a pig is castrated, his testicles are removed, thus removing the impetus for the hormonally-driven behavior and excretions. It may take a month or so after the surgery for him to completely stop the ejaculations and humping unless the humping has become a learned behavior at this point.
If the humping persists after the pig is neutered, try pushing him back from his shoulders or by creating loud noises that indicate the behavior is not acceptable. Pot-bellied pigs are relatively smart animals, so sometimes a firm "no" is all it takes.
Benefits of Neutering
Aside from the behavioral effects of neutering your male pot-bellied pig, you will also help prevent testicular and prostatic cancers from developing as well as prostatic infections and enlargement. Once your pet is neutered, he is less likely to roam in search of a mate. You needn't worry about the future of the pot-bellied pig population—there are plenty of these pigs available in shelters and through licensed breeders.
