Disease
Muscular dystrophy (MD) in Cavalier King Charles Spaniel, Golden Retriever and Norfolk Terrier is a spontaneous, X-linked, progressively fatal disease of dogs and is also a homologue of Duchenne muscular dystrophy (DMD). Affected dogs show raised creatine kinase levels, muscle atrophy with contractures, hyaline myofiber degeneration with mineralization, endomysial and perimysial fibrosis with fatty infiltration, and cardiomyopathy. Landseer muscular dystrophy (LSMD), in difference, is inherited as an autosomal recessive trait. Affected dogs exhibit a general, whole body muscular weakness, they move slowly and clumsy and some cannot walk at all. First symptoms in the course of movement appear at the age of three to six month. The disease is fatal in the first year of a dogs life.
