Most intact males will get erections from time to time, and this can cause inadvertent trauma to the penis due to pure friction against the penile sheath. Unfortunately the only way to stop this is to either lube the pets penile sheath daily to hopefully help reduce this friction, or to have the pet neutered. But keep in mind it can take up 2 months post-neuter for the testosterone levels to decrease enough to cause a reduction in unwanted sexual behavior. For now, if the bleeding has stopped, then you can try applying a cold compress onto the penile sheath for 5-10 minutes to help alleviate some of the irritation, and apply some KY jelly. However if there is significant swelling then it is best to get Teddy seen by your vet to get him on pet friendly anti-inflammatory medications. Then you can discuss possibly neutering Teddy to avoid this in the future.

    Bleeding from the penis can be caused by injury, infection, bleeding disorders (tick disease, auto-immune, toxin), urethral prolapse, urinary stones, among a few other causes. If the penis does not go back into its sheath where it belongs, you need to try to help him by using a water based lubricant such as KY jelly. You can mix it with sugar to help reduce swelling and gently pull the skin over it to protect it. Unfortunately, he needs a vet examination so we can find out exactly what is going on so that the appropriate treatment can be started.
