Half and half is simply half whole milk and half cream. In the UK, they call it half cream. According The Kitchn, half and half typically has a 10 to 12 percent fat content, which, it stands to reason, means it's less fatty than cream and fattier than milk.
Dogs can eat peas safely. Peas are a good source of potassium, zinc, iron and several vitamins. Depending on the size of the dog, 1 or 2 tablespoons of peas is recommended. The dietary fiber in peas also helps overweight dogs feel full thereby reducing the dog's intake.
Me: I would definitely avoid chocolate, onions and grapes. Client: GRAPES? Oh no, my dog eats grapes all the time! Have we damaged her kidneys? I have heard of so many dogs that eat grapes very often and never have kidney problems. And then, I've read of stories where a dog ate one grape and went into kidney failure. This is the rarity though. My point is that the odds are in your favor. The vast majority of dogs can handle grapes just fine. (In saying that I wouldn't go giving grapes to a dog on purpose.) I don't think you need to do anything further with Honey.
