Okay knitters - need your help brainstorming for Burke-patterns!

I am looking for something to knit for Burke!  I don't want to do a sweater - that's a bit much for him (not sure I could fit the harness over it) and for me (never knitted in the round before, much less a sweater).  So. . . collars?  Leashes?  Any other ideas, maybe a dog blanket?  Patters anyone?  
Thanks for any ideas!  :)
