Cerebellar Abiotrophies (CA) or "Ataxias" are genetic diseases in a number of dog breeds (and horses, people etc). They result in degeneration in the brain leading to the loss of muscle control and balance, ataxia, high stepping, wide stance, incoordination, falling over, difficulty jumping onto objects, fine tremors, a nodding head, difficulty eating or drinking from a bowl, and, occasionally, seizures.

Three particular types of CA are found in Kelpies (two of these also in Border Collies and likely Koolies).

With tests now available for CA, the number of CA affected pups being born can be greatly reduced.

In every mating, for each CA type, one parent must be clear.
