Summary
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.
About Welsh Terrier
Medium-sized, sturdy Welsh terrier with a wiry black-and-tan coat that sheds little but needs regular stripping. Bred in Wales to hunt, it is active, bold, affectionate yet independent, with strong chase instincts. Intelligent and trainable, it thrives on firm, positive guidance and daily exercise.
