Sealyham Terriers have no significant health problems. As with any dog, however, there are some conditions and diseases that Sealyhams could be prone to, such as lens luxation and retinal dysplasia.
- Lens Luxation. The lens of the eye can become displaced when the ligament holding it in place deteriorates. It's sometimes treatable with medication or surgery, but in severe cases the eye may need to be removed.
- Retinal Dysplasia. This is a developmental malformation of the retina that the dog is born with. Most cases are mild and there is no detectable loss in vision. Veterinary ophthalmologists can do tests to determine if puppies are affected when they are 7 to 12 weeks old. Retinal dysplasia shouldn't affect a dog's ability to function as a companion, but affected Sealyhams shouldn't be bred.
Although these ailments are rarely reported in Sealyham Terriers, you still should research breeders and find those who do the appropriate tests on their breeding stock to ensure that you get the healthiest dog possible. A breeder should be able to show you certification from the Canine Eye Registry Foundation (CERF) that the eyes are normal.
