I first fell in love with the full sized version when I was very young. I have had several over my lifetime. I love all sized of the Australian Shepherd but the large toys are my favorite. They still have the herding mentality and the bone to be able to move stock. Yes my dogs can and do herd horses, cattle and goats (soon to be sheep). I love the compact size of the toys where they can keep from getting kicked(most of the time hooves sail right over them) Toy Aussies are also great traveling companions.
