Cavalier King Charles Spaniels
Their health risks: At first glance, Cavalier King Charles spaniels may not look as recognizably unhealthy as some other breeds, such as a constantly panting bulldog. But they’re also brachycephalic, and they have their own laundry list of elevated health risks. In particular, most spaniels will inevitably develop mitral valve disease, which causes the valve to not close properly, allowing blood moving through the heart to sometimes flow backwards. The condition often leads to other heart problems, including heart failure, and it’s considered to be the breed’s leading cause of death. The Cavalier King Charles spaniel was the other breed beside the English bulldog that Norway decided to ban this year.
