Spinal Dysraphism (NTD) is a genetic disorder affecting the Weimaraner breed which is inherited as an autosomal recessive disorder. It is characterised by neural tube defect.
The onset of symptoms is usually at 4-6 weeks of age. Affected puppies are unable to move their back legs in the normal way and are unable to walk or run, they drag themselves by the front limbs. As they grow and get stronger they start moving their legs simultaneously like a bunny hopping.
Other neurological symptoms include ataxia, lack of coordination, wide based stance and abnormal spinal reflexes.
Spinal Dysraphism is not a painful disease and it is non progressive which means that symptoms will not get worse over time.
Genetic testing is available to identify the causative mutation.
