Thanks for the inquiry. Their parent both weigh right at 19 or 20 pounds. I don't know if you are familiar with the toy/mini Aussies, but they are just like the standard Australian Shepherd, only in a smaller package. We have never trained the parents to herd our cows, but the male just does it naturally. He also loves to swim, fetch and if you ask him if he wants to go fora ride, he hops right in the truck. The beauty of it is that you can pick them up and not hurt your back. If you want to give them a bath, just put them in the sink! They have the best disposition, especially around children. Please free to ask any other questions you might have!
