The survey of 1,019 dog owners was conducted by petbuzz in December 2022.
Veterinary cardiology specialist, Dr Rachel James, said: “The CKCS has long been a very popular breed of dog in high demand, due to their loving and placid nature making them perfect family pet.
"We know that sadly at least 50% of CKCS have evidence of MVD disease by the time they are five, with 98% of dogs affected in their lifetimes.
"However, we can help our clients when selecting this breed to choose a puppy that is less likely to develop MVD at an early age, by utilising the heart testing scheme (Doppler heart testing).
"Prospective owners should be asking to see test results for the parents, grandparents, and even better great grandparents too, on both maternal and paternal sides.
"In addition breeders need more support and education to encourage the use of the heart testing scheme and how this can enable them to choose the best dogs to breed from.
"Furthermore we should be encouraging breeders to breed from dogs only when they are at least 3 years of age.”
Vita Animal Health commissioned the survey to raise awareness of the condition and to remind owners to use their vet’s expertise.
Vita’s veterinary nurse, Tara Evans, said: “The CKCS is a very popular breed of dog, perhaps set to be more so now King Charles III is reigning monarch.
"This survey has shown that awareness of mitral valve disease – which is very common in this breed – is not as good as it could be.
"We want to support vets in raising awareness and have useful resources such as our heart disease infographic (www.vitaanimalhealth.com/common-signs-of-heart-disease) that we welcome all vets in using.”
