Summary
About Tibetan Mastiff
Ancient Himalayan guardian breed, large and powerful yet agile, with a thick weather‑proof coat and lion‑like mane. Calm indoors but strongly territorial and vocal when guarding. Deeply loyal, independent, aloof with strangers, and best suited to experienced owners.
About Sealyham Terrier
Compact Welsh terrier bred for hunting but affectionate and calm at home. Sturdy, low body with a distinctive white double coat, beard and eyebrows needing regular grooming. Intelligent, independent and moderate in exercise needs, it suits engaged families; the breed is now relatively rare.
