Summary
About Landseer
The Landseer is a giant, black‑and‑white water rescue and companion dog, calmer and more athletic than a Newfoundland. Gentle, people‑oriented and usually excellent with children, it needs space, regular grooming, steady training, and active owners willing to handle drool, mud and shedding.
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.
