What Does the Term Blue Merle Mean For a Cavapoo?
The term Blue Merle relates to the bluish color that Cavapoo dogs have between the patches in their coat. The colors range from a nearly powder blue look to a dark grey pattern. These Cavapoo puppies end up with a bluish coat color due to the Merle gene, which we discuss further below.
What Exactly Is the Merle Gene?
The Merle gene is a dominant one with the capital M denoting it. Non-merle is a recessive gene with a lower-case m showing the condition. You can have an MM homozygous dominant Merle dog or an Mm heterozygous dominant Merle canine.
The Merle gene makes the coat color more diluted and lighter than the dog would have if the gene were absent. The dog would have colored patches on their fur with jagged edges. The Merle gene also impacts the health problems of these dogs.
How Does the Merle Gene Impact a Typical Dog Like the Cavapoo
The most common health problems the Merle gene leads to are deafness, deformed eyes, blindness, skin cancer risks, and sun sensitivity. The nerve cells in the dog’s ears can have a drop in its blood supply and may even die.
Dogs with a heterozygous Merle (Mm) gene are less likely to have health problems, and canines with homozygous Merle (MM) genes are more likely to face health issues. B breeding two Merle dogs together is a bad idea, as it can lead the puppies to even more health problems.

The Problems and Health Risks of Mating Double Merles
