Quite often the retained testicle is sitting right in the channel but has never completely dropped into the scrotum. Reasons for this could be an obstruction in the scrotum or even a shortness of the cord attached to the testicle. Not all of these are in this position. Some are retained in the abdomen and should be surgically removed as soon as possible since retained testicles are predisposed to develop Sertoli cell tumors. Dogs that have retained testicles, even if one is dropped into the scrotum, should not be bred since cryptorchidisn is considered an inherited trait.
Boxers also suffer from ulcerative keratits.
This condition causes ulcers to appear on the cornea and is unique to the breed. Usually consisting of small, superficial lesions, ulcerative keratits doesn t have a tendency to spread. Hormonal therapy has been shown to reduce the chances of recurrence. As one of the deep chested breeds, the Boxer has been shown to be a candidate for gastric torsion or bloat. Bloat is a condition that causes the stomach to flip over and cuts off circulation to the area.
