It's really important that your dog gets the right diagnosis, quickly. In a survey among Dachshund owners on our Facebook Group, only half the IVDD cases were correctly diagnosed by their general practice vet on first presentation. Shockingly, a quarter of vets incorrectly diagnosed the problem, for example saying it was muscle pain, arthritis or a stomach problem. Some dogs have presented with anal gland problems which the vet may empty but the underlying pain, due to IVDD, remains. A further quarter of vets were unsure about the symptoms at first examination.
This is a condition more usually found in toy breeds but has been reported in Dachshunds (through our online health reporting system). Symptoms include neck pain, crying, yelping and rigidity of the neck. While it can be detected by X-ray, it is usually confirmed by CT scan and can either be treated conservatively or with surgery.

Myelomalacia is a condition that can occur after a spinal cord injury. It is more likely to develop in dogs that have complete paralysis and sudden loss of deep pain sensation (Grade 5). Read more here.
Meningitis is an inflammation of the membranes that cover the brain and spinal cord. It can be caused either by bacterial or viral infections, or it may be an immune-medited response. Signs include loss of appetite, fever, lethargy, genaral pain, and stiffness in the neck. It is, generally, rare in dogs and this would be an unusual diagnosis in a Dachshund. More information here.
