Summary

About Irish Wolfhound
Irish Wolfhounds are giant, tall hounds with a strong yet graceful build and a rough, weather‑resistant coat. Calm, gentle and sensitive, they are low‑key indoors but need steady exercise and space. They have notable health risks and a relatively short lifespan, so careful breeding and care are vital.
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.
