Sealyham Terrier: temperament & character

The Sealyham Terrier is confident, brave and independent-minded, while being very affectionate and playful with its family. It often meets strangers with reserve and alert barking.

How much exercise does a Sealyham Terrier need?

Despite its compact build, it needs daily walks and occupation, having originally been bred for fox and badger hunting. Digging and scent games are among its favourite activities.

Sealyham Terrier: grooming & shedding

The wiry coat must be regularly hand-stripped or clipped to maintain its texture, and it sheds very little. Without professional grooming every few months, it quickly mats or grows unruly.

Is the Sealyham Terrier suitable for beginners?

Its stubborn terrier character and pronounced independence call for consistent, patient training, so first-time owners should familiarize themselves thoroughly with the breed beforehand.

Sealyham Terrier health problems

The breed is considered robust, though the small population occasionally sees lens luxation and back problems. Regular eye examinations are recommended by breed clubs.

The Sealyham Terrier sheds little and is therefore considered comparatively well tolerated by allergy sufferers. No breed is truly hypoallergenic, though: the allergy is triggered by the protein Can f 1 in saliva and dander, not by the hair itself.
