![]() That does not mean your dog will have these problems it just means that she is more at risk than other dogs. There is a general consensus among canine genetic researchers and veterinary practitioners that the conditions we’ve described herein have a significant rate of incidence and/or impact in this breed. Many diseases and health conditions are genetic, meaning they are related to your pet’s breed. By knowing about health concerns specific to Cavalier King Charles Spaniels, we at Johnson Animal Clinic can tailor a preventive health plan to watch for and hopefully prevent some predictable risks. That is why we have summarized the health concerns we will be discussing with you over the life of your Cavalier. We know that because you care so much about your dog, you want to take good care of her. Your Cavalier King Charles Spaniel's Health The Cavalier King Charles Spaniel is a generally healthy breed with an average lifespan of 9-14 years. The Cavalier is an intelligent and fearless companion, but is not known to be a good watchdog even though they can alarm bark because they are often overly social with strangers. The Cavalier King Charles Spaniel thrives in a home where someone is home most of the time they require close human contact and often become destructive when left alone more than a couple of hours. When not on the move the Cavalier’s favorite place is their owner's lap. The Cavaliers are an active breed that enjoys chasing butterflies in the yard and is even suitable for obedience trials. The Cavalier was separated from the King Charles Spaniel, or English Toy Spaniel, in the early 1900’s in an effort to return to an older variant with a longer muzzle. The Cavalier King Charles Spaniel originated in England as a companion pet. With early socialization and consistent leadership, she is a patient and happy addition to any family. She is a lover of comfort and is devoted to her family. An indoor dog that doesn’t do well in the heat.Sees cats and small animals as prey unless trained otherwise.Exhibits signs of separation anxiety if left alone too much.Needs frequent attention from her family. ![]() Intelligent, eager to please, and responsive to training.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.If you think Cavalier King Charles Spaniel is a regal name for a regal dog, then you're right! Lots of things make these pups special: 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.
