Penis Trapped Outside Sheath (Paraphimosis)

Condition Overview

In dogs with this condition, the extended penis is unable to return to its former position inside the sheath. Long hair on the skin around the sheath causes the foreskin to roll under so that the sheath cannot slide.

Symptoms

The penis will be unable to return to its "resting" position.

Causes

This usually happens after the penis has been extended during mating. The sheath then serves as a constricting ring around the shaft of the penis, causing sustained engorgement. A rubber band placed maliciously around the shaft of the penis would produce a similar result.

Diagnosis

Diagnosis is made by evaluating symptoms.

Treatment

The penis must be returned to its normal position inside the prepuce as quickly as possible to prevent further swelling and permanent damage. First, lubricate the shaft with K-Y jelly, mineral oil, or olive oil. Push the prepuce back on the shaft of the penis while rolling it out to release the trapped hair.

1. With one hand, gently draw the head of the penis toward you.
2. With the other, slide the prepuce forward over the head of the penis.

Prevention

Paraphimosis can be prevented by cutting the long hair around the foreskin before breeding. Always check the male after mating to be sure the penis has returned to its sheath.
