A young Alaskan Malamute that tires unusually fast, stumbles or loses tongue muscle bulk may have a hereditary neuromuscular condition specific to the breed, well identified through genetic research. Find all our enrichment ideas in the dog toys and enrichment section.

What the landmark study shows

Bruun and colleagues published a study in 2013 in PLoS ONE identifying an NDRG1 gene mutation behind hereditary polyneuropathy in the Alaskan Malamute (study on Google Scholar). Dogs carrying two copies of the mutation progressively develop muscle weakness, growing exercise intolerance and, in some cases, visible tongue atrophy, with signs typically appearing before adulthood and worsening over time.

Frequently asked questions

Does every Alaskan Malamute face this condition?

No, only dogs carrying two copies of the mutation develop the disease; a genetic test can identify healthy carriers.

Can the condition be reversed with the right treatment?

No, there is currently no cure; management mainly focuses on adjusting the affected dog's activity level and comfort.

Can a still-active puppy already carry the mutation?

Yes, early signs develop gradually and can go unnoticed in a young puppy that still seems very active day to day.
