Phimosis (Strictured Foreskin)

In dogs with this condition, the opening of the sheath is extremely small, preventing the penis from extending and in some cases interfering with the flow of urine. Neonatal phimosis is a birth defect that occurs most often in German Shepherd Dogs and Golden Retrievers. Several pups in the litter may be affected. Adult phimosis can be caused by a sheath infection or a congenital defect.

Treatment: Some cases of phimosis resolve with treatment of the associated sheath infection. Most will require surgery to enlarge the opening. Neonatal phimosis causing urinary tract obstruction requires immediate relief.
