Summary
About Neapolitan Mastiff
Ancient Italian giant guardian with massive build and heavy wrinkles. Calm and affectionate with family, wary of strangers, and protective by nature. Needs early training, steady leadership, moderate daily walks, and careful skin and drool care due to size and loose folds.
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.
