Thanks for all that, my little man Merlin licks only one of his paws on a pretty regular basis. 
You guys are mostly from the States and I don't think that I get the stuff you can buy over there here in the UK. I want the best for my two little men and hope that you can give me a couple of ideas what to get best. Mind you, choose little tinkers, don't like the dry stuff too much, they prefer the meaty bits.
Seems there is an awful lot of knowledge out there to be shared, I am glad to became a member!
