Figure 2.

Representation of distributions of fibrotic lesions within the ventricular wall of Golden Retriever muscular dystrophy (GRMD) dogs using a trichrome stain which stains collagen blue and muscle fibers red. (A) The sub-epicardial myocardium (male, 3-years-old) is reportedly preferentially affected in GRMD dogs (pictured) and Duchenne muscular dystrophy boys (not pictured). (B) However, the mid-myocardium (male, 4-years-old) may predominate. (C) Subendocardial changes were rare and only seen in the right ventricle (female, 1-year-old).
