Care in detail

🍽️ Nutrition

Quality small-breed food in 2 meals, with portion control: it is compact and short-legged, easy to overfeed, and excess weight punishes its long back. Lean treats and no fatty leftovers.

✂️ Grooming

A wiry, double, white and eye-catching coat: brush 2-3 times a week and hand-strip every 8-10 weeks (or clip). Keep the beard clean and check the furnishings; white hair stains and requires careful baths and thorough drying.

🎓 Training

Calmer and more thoughtful than the average terrier, but with an independent streak. Responds well to positive reinforcement, short sessions and patience. Socialise it as a puppy: it tends to be reserved and watchful with strangers.

🏃 Exercise

45-60 minutes daily split between walks and scent games. It has moderate energy for a terrier: it enjoys tracking and digging, but is content with less exercise than a Welsh or a Fox. Ideal for anyone wanting a terrier without so much drive.

Breed-specific health
