Dog’s penis not retracting

I adopted an approx. 5 year old male long-haired chihuahua. He is about 4 lbs. He had not been neutered until the rescue group received him at the end of July. His penis protrudes rather considerably from the foreskin. I have had him groomed & checked for fur/hair blocking the foreskin. There is no sign of infection. All his stitches are gone now too. Do you recommend surgery? I have read a stitch or two can cure the problem.

 

Answer from Dr. Gaylord Brown:
Surgery can correct this problem and it is recommended. The constant exposure of the delicate skin of the penis will lead to medical problems. We generally correct this at the time of neutering.
