Summary
About Australian Shepherd
The Australian Shepherd is a medium, athletic herding dog, highly intelligent and energetic. Loyal and people oriented, it bonds closely and needs substantial daily exercise, training, and mental work. Its striking, weather resistant coat and varied eye colors add to its appeal.
About Spanish Mastiff
Large, powerful livestock guardian, calm and observant yet strongly protective. Quiet and laid back at home if well exercised, deeply loyal with family and usually reserved with strangers. Independent and thoughtful, it suits experienced owners with space, structure and early socialisation.
