Things to keep an eye on

Intervertebral Disc Disease (IVDD)

high

Due to their long backs and short legs, this breed can be prone to disc issues in the spine. This may manifest as stiffness, reluctance to jump, or changes in gait.

Maintain a healthy weight and use ramps or stairs to help your dog avoid jumping on and off high furniture.

Lens Luxation

high

This condition occurs when the ligaments holding the eye's lens in place weaken, causing the lens to shift out of position. It can lead to discomfort and vision changes if not addressed promptly.

Schedule annual eye examinations with a veterinary ophthalmologist to detect early signs of lens instability.

Dental Disease

moderate

Like many small breeds, Sealyhams can accumulate plaque and tartar quickly, which may lead to gum inflammation. Consistent oral hygiene is essential to prevent long-term complications.

Brush your dog's teeth regularly with pet-safe toothpaste and provide appropriate dental chews.

General patterns, not a diagnosis — always check with your vet.
