Blue merle Border Collie puppy Red merle Australian Shepherd. Merle is a genetic pattern in a dog's coat and alleles of the PMEL gene. It results in different colors and patterns and can affect any coats. The allele creates mottled patches of color in a solid or piebald coat, blue or odd-colored eyes, and can affect skin pigment as well. Two ...
Blue eyes in dogs are often related to pigment loss in coatings. The merle gene results in a bluish iris, and merle dogs often have blue, walled, or split eyes due to random pigment loss. Some genetic variants cause Heterochromia iridum. [68] The second way blue eyes can appear is when a dog has a lot of white fur on the face.
It can also be a behavioral problem characterized by attention-seeking, reinforcement, or as a learned behavior. Numerous health problems can arise from this activity, including internal parasites or infection with canine parvovirus or toxoplasmosis. Treatment includes behavioral modification therapy or altering the feces to affect its taste. [169]

Based on a sample of 48 still-living dogs, the most common health concerns noted by owners were eye problems (red eye, epiphora, conjunctivitis, and cataracts).

In 2019, many Koolie breeders took part in the research project to find a DNA test for the Merle gene, as it was believed many non Merle looking dogs could be genetically a Merle and therefore have issues when bred to a Merle. The breeding of two Merle dogs runs a high risk (in all breeds) of sight and hearing defects in the offspring.
