Congenital laryngeal paralysis (CLP) is described to be hereditary and occurs either as part of a polyneuropathy complex (LarPar-PNC) or as single condition.Affected dogs should undergo a complete general, orthopedic and neurological examination, if possible including electrodiagnostics. Complete blood work, cervical and thoracic radiographs, contrast esophagraphy and videolaryngoscopy should precede unilateral arytenoid lateralization (UCAL). Muscle and nerve biopsies should be taken in both dogs undergoing surgery as well as dogs that may have to be euthanized.The Alaskan husky is a breed affected by CLP. The typical phenotype associated with this condition includes blue eyes and white facial markings.The prognosis for dogs with LarPar-PNC is poor. In contrast, dogs solely affected by CLP - such as the Alaskan husky - have a good prognosis when treated surgically.
