Ataxia

Ataxia is a loss of coordinated movement, seen as a wobbly gait, swaying, stumbling, or difficulty placing the feet accurately.

The word describes a sign rather than a single disease. Coordination depends on the cerebellum, the inner ear, and the nerves that report limb position, and a problem in any of these can produce ataxia. In dogs and cats, owners typically notice a drunken-looking walk, crossing of the legs, a wide stance, or a head tilt. Veterinarians assess ataxia with a neurological examination and, depending on the findings, imaging or blood work to locate the cause.

Ataxia is one of the most common signs reported when pets are accidentally exposed to THC-containing cannabis, and it has also been recorded in some canine studies of cannabinoid administration. Because it can also indicate poisoning, infection, injury, or vestibular disease, sudden ataxia in an animal is treated as a reason for prompt veterinary attention. Owners are encouraged to tell the veterinarian about any substances the animal may have reached, including cannabis or hemp products in the home.
