Health Problems of Cavalier King Charles Spaniel versus Health Problems of Leonberger
Every dog breed has its own set of health problems that it has a tendency to develop. There is nothing like a perfect dog breed.
Both the Cavalier King Charles Spaniel and the Leonberger are prone to certain genetic health conditions. The Orthopedic Foundation for Animals (OFA) is the organization that keeps track of health problems in dogs. Based on the extensive records that the OFA keeps, the OFA knows what health problems each dog breed is naturally prone to develop. Hence, the OFA recommends which health screening that breeders should perform on a dog breed to make sure that the breeders won`t breed `defective` dog parents that can pass down defective genes to their puppy offspring.
The more health problems a dog breed is prone to develop, the more health tests the OFA will recommend for that dog breed.
Based on our review of OFA records, we found that the Leonberger is prone to more genetic health problems than the Cavalier King Charles Spaniel.
This is because the OFA recommends more screening health tests for the Leonberger than for the Cavalier King Charles Spaniel.
4 health tests are recommended for Cavalier King Charles Spaniel while 10 tests are recommended for the Leonberger.

If you want a Cavalier King Charles Spaniel puppy that will grow up to be healthy, make sure that your Cavalier King Charles Spaniel breeder screens your puppy or your puppy`s parents for the health problems that the OFA recommends for your puppy`s breed.

Again, most of these health problems can be prevented through health screening. Responsible breeders screen male and female dog parents for genetic problems. These breeders will only breed dogs that are free of genetic defects. That way, there is little or no chance that their puppies will grow up to have genetic health problems. Always ask a breeder for the list of health tests the breeder screens their dogs for before buying a puppy from such a breeder.
