Cadbury's has its place, I admit. There are days when a bar of Dairy Milk is just exactly what I fancy, and nothing else will do. However, the cocoa content is so incredibly low that in parts of the world it actually has to fight to be classed as "chocolate" - really, it's chocolate-flavoured sugar and fat and a bit more sugar and the much vaunted "glass and a half of full cream milk". You shouldn't feed chocolate to dogs - it's poisonous to them. Feed a 200g bar of Cadbury's Dairy Milk to a dog and it'll just go nuts on the sugar for an hour or so. There's not enough chocolate in there to have an effect. Go and try some quality milk chocolate with a cocoa content of at least 50%. This is a good one to start with. You'll never look at Cadbury's in the same way ever again.
