common health issues

Inherited deafness in one or both ears occurs due to the degeneration of the structures of the inner ear. It usually occurs within the first few weeks of birth. Deafness is tied to coat color, especially in merle pups, and has an association with blue eyes. Hearing tests can be conducted at referral centers or veterinary schools, but inherited deafness is permanent and cannot be cured.
The retina lines the back of the eye and is responsible for transmitting visual stimulus to the brain. Retinal dysplasia is a malformation of the retina which can range from mild retinal folds to severe dysplasia with detachment of the retina and blindness. Visually impaired dogs generally adapt to life well due to their keen sense of smell.
Normally, the lens of the eye is held in place between the iris and the retina. A luxated lens lies in an abnormal position, either backward or forward of it's normal position. Treatment ranges from conservative treatment to removal of the affected eye.

The Sealyham Terrier originated in Wales, developed in the mid- to late 18th century by Captain John Edwardes at Sealyham House, Pembrokeshire. He is descended from a mix of several breeds, including the West Highland White Terrier, Wirehaired Fox Terrier and Bull Terrier, to hunt badger, fox and rats. He enjoyed enormous popularity in the UK and US alike after World War I, and was the preferred companion of King George V, Alfred Hitchcock and Elizabeth Taylor. Today, though, his numbers have dwindled, and efforts are underway to increase the Sealyham Terrier population in the UK.

Sealyhams are small, standing only about a foot high at the shoulders and weighing around 20 lbs. His all-white double coat includes a softer undercoat and a wiry, weather-resistant outer one, and he does require regular brushing and trimming to keep mats at bay. The Sealyham adapts well to both town and country living, provided he gets a dose of daily exercise. Like most terriers, he is loyal, spirited and determined (some would say bullheaded!), so he requires plenty of obedience training from puppyhood.

Although a generally healthy breed, Sealyham Terriers are still prone to some hereditary and congenital conditions that can adversely affect their health — not to mention your family budget. Some of the conditions and illnesses Sealyhams are prone to include eye conditions such as retinal dysplasia and lens luxation; hearing problems such as deafness; and neurological conditions such as dengenerative myelopathy.

Thankfully, Petplan pet insurance covers all hereditary and chronic conditions as standard. Which means if your Sealyham inherits more than a stubborn streak, you’re covered.
