Hi.  First time on Cake Central.  What a cool place!  I have to make a chow chow dog sculptured cake and I am nervous.  I have researched techniques and think I will do it sitting on its hind legs.  I plan on the body being cake and the head being cake.  The muzzle, tail and front legs will be rice crispie.  Two questions...which technique for fur should I use and how far in advance can I make the rice crispie part of it?  Any advice would be much appreciated...I am new to all of this.
