Summary
About American Hairless Terrier
Small, lively terrier available in hairless and coated forms, usually 25–46 cm and 5–12 kg. Very people-focused, indoor-oriented, and low-shedding, often suiting allergy-prone owners. Needs moderate daily exercise, mental stimulation, skin protection, and consistent, positive training.
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.
