Q. My un-neutered, male dog has an erection that will not subside. What could be the cause?
DR. CHRISTIE LONG, D.V.M., C.V.A.
A. The medical name for this is "paraphimosis". You didn't mention your dog's age, but sometimes it happens in developing dogs that still have a small prepucial opening - that's the skin that covers the penis that keeps you from actually seeing the penis most of the time. They can also have something called hypospadia, which means the urethral opening isn't in the right spot on the penis.
This can turn into an emergency, if the erection doesn't subside. I recommend going to the vet immediately. Usually we can use a glucose solution along with lubricant to get the erection to go down and the penis to go back in. I don't recommend trying this yourself, as it can be painful to the dog. Neutering your dog will take care of this problem. Otherwise it can become a chronic problem.

A. This is not uncommon but is a medical emergency to prevent permanent damage or self trauma. You can attempt to run a cold hose over the area for 5mins but if this does not resolve the issue he will require urgent sedation, replacement and suturing before any nerve or blood vessel damage occurs
