I agree with the general consensus, it's worth changing his food. Milo has been a REALLY hyper, snappy puppy (was being fed on eukanuba) and a COL member recommended I try Burns and he has improved beyond belief in about 3 days! He is obv still daft as a brush and abit hyper but now I can tell what he wants by it, for example he gets stoopid if he's hungry, tired, needs the toilet or he wants to play!
