Common health problems
This section describes conditions the breed is known to be predisposed to, so you know what to ask about. It is not veterinary advice and is not a diagnosis — always speak to a vet about your own animal.
- Globoid cell leukodystrophyA DNA-testable neurological disease — ask breeders for results.
- Portosystemic shuntA liver blood-vessel abnormality seen in the breed.
- Ocular melanosisPigment build-up in the eye that can lead to glaucoma. Annual eye checks are worthwhile.
- Patellar luxationSlipping kneecaps, common in small breeds.
- AllergiesItchy skin occurs and warrants a vet plan.
Ask breeders about globoid cell leukodystrophy testing and eye screening for ocular melanosis.
Interesting facts

Diet & Feeding
Feed around 130–210 g of quality small-breed food daily across two meals. Cairns are food-motivated and gain weight if under-exercised. Keep them lean and count treats.
Exercise Needs
About an hour a day of walking and play. Cairns are curious and energetic and love to dig and explore. Prey drive is strong — secure areas are needed off lead. Provide a digging spot or scent games to channel the instinct.
Grooming
The shaggy coat is meant to look natural. Brush weekly and hand-strip twice a year to remove dead hair; clipping softens the coat. Bathe rarely. Trim nails every three weeks and check ears weekly.
Health & Vet Care
Generally healthy and long-lived. Watch for globoid cell leukodystrophy (a DNA-testable neurological disease), portosystemic shunt, ocular melanosis which can lead to glaucoma, patellar luxation and allergies. Ask breeders for DNA results and eye screening.
Training Tips
Cairns are bright and independent. Reward-based, varied training works well. Work on recall in safe areas, teach a quiet cue early and socialise with other dogs and cats from puppyhood.
