Great job! I bet that you can't keep your hands off of him now! They feel so good after a clip.....
Petedge is VERY reasonable with grooming supplies...
I use a #30 with a clipper comb. You could also use a #10 that comes with your clipper it too.

They have some great deals on blades too if they fit your clippers... I love the old standard, the Oster A5 golden single speed.
