I'ts a few weeks yet till my pup comes home and I haven't yet checked what type he's being fed. We have fed Wafcol in the past to our previous dogs, but I would like some ideas on what are the best makes of complete dried food.

I don't know about the best food as the best food for your puppy is the one that agrees with him the most!

I would just keep him on the food that he is eating at the moment for a while.

I'm just going to repeat the above:

The best food which suits your pup is the best food :) (and also what you can afford)

Find out what he is on for the moment and then either keep with that for AT LEAST a couple of weeks, or just continue with it :)
