Chocolate labs are more desirable than their black and yellow counterparts. The brown color is caused by the homozygous recessive genotype. This genotype is associated with shorter life spans and predisposition for health issues. Studies done have found that chocolate labs live on average a whole year less than their brown and black siblings. They also have increase of ear and skin infections on top of the typical join issues that labs typically have. Because these dogs are highly sought after, these genes are making the Labradors an unhealthy breed of dog. An article on AllThingsDog.com stated that because these dogs are continuously interbred for their color, they are showing increased risk of genetic health issues due to their limited gene pool. I think that breeding dogs for looks does dogs in general a disservice. Breeding health issues into them is cruel, especially because most dogs are not bred for a specific purpose. Most are just family dogs. I think that people should adopt dogs rather than shop to stop funding breeding like this.
