I am not quite sure how measure. I would say around 20" at the withers, but he is much bigger than any of the other dogs from his litter.
I have had full sized Aussies before as well. Imagine taking that energy and compressing it to a singularity that is always ready to explode. That is Rufus and I wouldn’t trade him for the world.
I found Summit about 2 hours ago and love it! Thanks for your hard work.
