Summary
About Border Terrier
Small, sturdy terrier originally bred on the England–Scotland border to hunt foxes. Affectionate, bonded to family, yet independent with strong prey drive. Needs 1–2 hours of daily exercise, secure fencing, and kind training. Wiry, weather-resistant coat needs brushing and occasional hand stripping.
About Pyrenean Mastiff
Large Spanish livestock guardian, the Pyrenean Mastiff is a giant, steady dog with a dense white coat and dark patches. Calm, observant and deeply loyal, it’s affectionate with family yet reserved with strangers, needing space, firm but gentle training, and experienced ownership.
