Got talking to a guy last night in the next village who told me he keeps light, athletic Spanish Mastiffs (ligeros) that are used for guarding and large-game hunting, weighing in at around 40 kgs.The only Mastines I've seen have been huge, cuddly things, not very guardy to be honest, and I was wondering whether any of you guys had any knowledge of this lighter, working type? I've been invited over to check them out and I'm hoping to get across within a week or two so will report back.
