Myelodysplasia (spinal dysraphism)(SD)
Also known as: Spinal dysraphism · Spinale Dysraphie · Myelodysplasie · Canine spinal dysraphism · Spinal dysraphism in Weimaraners
Overview
What it is
Myelodysplasia, also known as spinal dysraphism, is a congenital malformation of the spinal cord where the nervous tissue fails to develop and close properly during embryonic growth. This defect permanently disrupts the transmission of nerve signals from the brain to the hind legs. Because the spinal cord is part of the central nervous system, this malformation directly impacts the dog's coordination and movement.
How it presents
Symptoms typically become noticeable between 4 and 6 weeks of age as the puppy begins to walk. Owners will usually observe an unusual, synchronous 'bunny-hopping' gait in the hind legs, though the condition is non-progressive and does not worsen over time.
Treatment
There is no cure for this condition, but it is painless and does not require lifelong medication. Management costs, including initial diagnostic imaging like an MRI and supportive care such as physiotherapy, typically range from 500 to 2500 EUR.
