Polymelia
Also known as: Supernumerary limbs · Polymelie · Congenital polymelia · Extra limbs in dogs · Überzählige Gliedmaßen
Overview
What it is
Polymelia is a rare congenital anomaly affecting the musculoskeletal system where an animal is born with extra, non-functional limbs. This developmental error occurs in the womb during embryonic growth, causing accessory legs to attach to areas like the shoulder, pelvis, or spine. Because it is a structural birth defect rather than an active disease, it does not spread or progress over time.
How it presents
This condition is immediately visible at birth, as the puppy will have one or more extra legs attached to its body. Owners will notice these additional limbs, which typically cause abnormal posture, restricted movement, or difficulty walking as the puppy grows.
Treatment
The condition is treatable through a one-time surgical procedure to amputate the extra limbs, which helps restore normal mobility. The total cost for diagnostics and surgery typically ranges from 1,500 to 6,000 EUR.
