Cavalier King Charles Spaniels come in four colors. The breed was even named for the monarch.
He issued a royal decree that the dogs should be allowed in all public spaces, including Parliament. Charles II was so attached to his spaniels that they went with him everywhere. They’re named for royalty.īoth King Charles I and his son, Charles II were devotees of the breed. Best not to let them off-leash when out and about and to have a fenced yard at home.Ī combination of athleticism and trainability help the Cavalier King Charles Spaniel excel at sports like agility, rally, and obedience. They may be so intent on the chase that even a well-trained dog may not come when called. Yes, they’re lapdogs, but they’re also sporting dogs.Ĭavs retain their original hunting instincts and can be off like a shot after small creatures or if they catch a scent. Originally bred as companion dogs, it’s only natural that they excel as therapy dogs. If your Cav has a loving, warm temperament and you have the time and dedication to work with him, consider the AKC Therapy Dog Program. Cavalier King Charles Spaniels makes great therapy dogs. The warm, dark brown color of their eyes and the cushioning under the eyes create a melting, limpid look which contributes to their gentle expression. The beautiful large round eyes are a breed hallmark. In fact, strangers are friends they haven’t met yet. They are one of the friendliest breeds, showering affection on their family and happily getting along with other dogs, kids, cats, and total strangers. Not convinced? Check out some of the things Cav owners would tell you. Cavalier King Charles Spaniels combine the lovable traits of a companion dog with the lively sporting instincts of their ancestors and are beloved, popular pets today. In the Cavalier King Charles spaniel specifically, one or several of these mutations affect heart muscle protein NEBL and may predispose this breed to devastating heart disease.This gentle, affectionate breed won over royal hearts as early as the 17th century. The bottlenecks may have made the harmful genes more common in the cavalier King Charles spaniel genome before the dog achieved recognition as a breed in 1945.Īxelsson adds, "We find that recent breeding may have led to an accelerated accumulation of harmful mutations in certain dog breeds. These spaniels experienced several "bottlenecks" where only a small percentage of the population passed on their genes to the next generation. Records suggest that small spaniel-type dogs have existed for at least 1,000 years and were popular at royal courts for several hundred years throughout Asia and Europe, including at the court of King Charles II (1630-1685).
The especially large number of potentially harmful genes in the genomes of cavalier King Charles spaniels, compared to other dogs, likely resulted from its breeding history. The findings offer a potential explanation for why the cavalier King Charles spaniel is predisposed to develop the disease. They identified two genetic variants linked to the disease, which appear to regulate a gene that codes for a common protein in heart muscle. In this condition, the mitral valve in the heart degenerates, allowing blood to leak from the left ventricle back into the left atrium. The researchers also looked for genetic variants in the cavalier King Charles spaniel genomes linked to MMVD. They found that the cavalier King Charles spaniel, which experienced the most intense breeding, carried more harmful genetic variants than the other breeds they examined. They sequenced entire genomes from 20 dogs from eight common breeds, such as beagles, German shepherds, and golden retrievers. The study's researchers wanted to know whether recent breeding practices had increased the number of disease-causing variants in dogs. Unfortunately, this process has also caused many breeds to become more inbred and more likely to inherit genetic diseases. The past 300 years of dog breeding have created an incredible diversity of breeds with various sizes, shapes, and abilities.
