When his owner noticed some unusual changes, they rushed straight in to have him checked over with us and then seen by the neurology department at the Animal Referral Hospital. After many tests including x-rays, MRI and a spinal tap, an unusual diagnosis was made – Neosporosis.
Neosporosis is caused by a protozoan parasite that can be picked up from contaminated food and water, or the ingestion of infected tissue. Infection is most common in puppies, where is can be passed on from the mother, causing the development of partial paralysis of the limbs. In older dogs, brain and spinal cord inflammation can occur and the development of pneumonia and myocarditis (inflammation of the heart). The MRI image shows the spinal cord inflammation, causing Cookie’s unusual walk. His clipped patch of hair shows the location where spinal fluid was sampled to confirm the diagnosis.
Although Neosporosis is very rare, especial in older dogs, it is thankfully very treatable if a quick diagnosis is made. With a combination of medications including steroids, antibiotics and parasitics, Cookie is now well on the way to a full recovery and exploring the great outdoors again.
