Phimosis is a condition that causes a dog to be unable to protrude its penis from its outer orifice. Paraphimosis, on the other hand, refers to the dog's inability to retract its penis back in to the sheath.
Both of these medical conditions can occur in male dogs and cats, and at any age. If you would like to learn more about how phimosis and paraphimosis affect cats, please visit this page in the PetMD health library.
The dog's inability to protrude its penis may go unnoticed until it tries to copulate with a female. Also, if the dog is having trouble urinating, it may be a sign of this medical disorder. If the animal experiences problems retracting its penis into the sheath, you may notice it licking the exterior of its penis. If it occurs over a prolonged period, there could also be fluid accumulation in the tissues (edema) or swelling in the area.
The inability to retract the penis (paraphimosis) often occurs when the dog has a small opening (orifice), and in many cases is a birth defect. If the dog is unable to protrude the penis (phimosis), it may have swelling, or hairs that are obstructing the penis. In some cases, injury or a neurological disease can cause this medical condition.
With paraphimosis, the veterinarian will be able to view the exposed penis and/or gland areas upon examination. The goal is to identify the underlying medical cause for the condition for treatment options.
