Small cubes of cheddar, tuna bread or sardine bread, or dry toast.
William has a slightly sensitive digestive system and I know from experience that cocktail sausages give him an upset tummy.
I won't feed him tinned hot dog sausages because I'm not too sure what's in them and wouldn't touch them with a bargepole personally
(but I am a fusspot when it comes to food). I don't like using most of the commercially made treats, again because I dread to think what they're made of.
I follow the same guidelines for Louis, but have to say that he seems to have a cast iron constitution. After all, a puppy who swallowed a Greenfinch whole and suffered no ill effects must be pretty robust
