Disproportionately longer lower jaws, multiple skin folds, sagging of skin, dental diseases and abnormally protruding eyes due to their flattened faces. These examples are seen in several other dog breeds (e.g Cavalier King Charles Cocker spaniels and French bulldogs) as a result of centuries of excessive inbreeding. Point A in the above photo shows protruding eyes which are irritated due to the skin folds in point B, which has therefore caused leaky tear stains at point C.
