Intestinal lipid malabsorption (ILM)
Intestinal lipid malabsorption (ILM) is a disorder sometimes found in Australian Kelpies (bench Kelpies). Affected puppies are usually called Kelpie mini pups. They are smaller than their unaffected litter mates, have dull and rough coats, big bellies, domed heads and round eyes.
Dogs with ILM cannot absorb long-chain fatty acids from their food like normal dogs.
ILM is an autosomal recessive disorder. Autosomal disorders can affect male or female dogs, while "recessive" means that a dog needs to inherit the ILM mutation from both parents to be affected. Carriers (dogs with an ILM n result) can safely be bred to clear dogs (those with an n n result) with no risk of producing affected pups. Carriers should not be bred to other carriers.
