Finishing Dog Feet

I'm finishing up the details on all 4 feet of my sculpture of a German shepherd dog (representing the many dogs C.W. Lonsdale had as Headmaster). My model for the body and feet is a white German Shepherd named, Finn. He is the sweetest and most well behaved dog I have ever had modeling for me. Julie (Finn's owner) does a good job keeping him still. Usually he models for me a couple hours at a time.
