You know the sort, really expensive, specially formulated taste, chunks of real prime beef, all that bullshit.
Does it make any difference at all? How do we know how dogs perceive taste? They literally lick their own arseholes and chocolate makes them sick, so preparing some gastronomic delight for them must be a waste of everyone's time. Can your dog tell the difference between Tesco Basic Nutri-chunks and the top end stuff?
Bunch of mugs.
