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.
