Abberration Splits Dog’s Left Leg in Two
AVON LAKE, Ohio (April 1) – A developmental problem split Angel the dog’s leg, making her look like a five-legged pet. Veterinarian Frank Krupka, with the Avon Lake Animal Clinic in suburban Cleveland, said he’s never seen anything like it.
After examining X-rays, Krupka determined that a genetic aberration split Angel’s front left leg in two, leaving her with three normal legs and two distinct parts of a fourth.
