Chondrodysplasia (CHD)

Chondrodysplasia, commonly referred to as “dwarfism” is a genetic disorder which manifests itself in puppies born with crippling deformities, eventually evident in the abnormal shape and length of their limbs.

For the Alaskan Malamute, it has been conclusively proven that CHD is genetically inherited through a simple recessive mode, meaning the sire and dam must both have this gene in order to produce an affected puppy. The Alaskan Malamute Club of America (AMCA) maintains a CHD certification program based on the dog’s pedigree, thus determining a percentage of probability.

The AMCA issues certificates for dogs with little probability of producing affected puppies. Through stringent and selective breeding strategies, it is possible to eliminate the disorder in the breed and only certified dogs should be bred to prevent the resurfacing of the disorder.
