Ullrich-like Congenital Muscular Dystrophy


Ullrich-like Muscular Dystrophy is characterized by progressive muscle weakness, laxity, and joint contracture.

  • Signs and symptoms

    This is a slowly progressive muscle disease characterized by non-painful muscle weakness and wasting, especially over their back and legs. Dogs eventually have difficulty walking. Problems with swallowing and breathing have been reported in other forms of muscular dystrophy, although it is unknown if they commonly occur in Ullrich-like Muscular Dystrophy.

    Signs are often first apparent at 5-6 months of age.
