What is lumbosacral stenosis?
Lumbosacral stenosis is a painful narrowing of the spinal column that can be congenital or degenerative. It can be treated successfully with surgery.
Is it common in Aussies?
No.
Is it inherited?
In most cases skeletal degenerative disease is due to wear and tear though the conditions that lead to the wear and tear may be inherited, as with hip dysplasia. If the cause was congenital (present at birth) there is a possibility it might be inherited, especially if it has been seen in more than one family member. It would probably be best not to breed dogs with the congenital form of the disease.
