Fancy a loaf

This advert is comical, they have picked the perfect bread of dog to match a loaf of bread, this advert is to warn about germs, to make sure you realise that what you touch is what you eat. Everyone strokes there pets and then immediately eat food, same as we touch other people and then eat.
I think it is effective but it's maybe too comical for people to take seriously, and there is a bit of cruelty as the dog does look sad, but in another way they haven't overly made it obvious that he's meant to be a load of bread (so you are essentially eating what you touch). The whole spectrum of this advert is that you subconsciously see him as bread same as you subconsciously eat after touching items.
