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.
Foods like vegetables and some soft fruits should be okay for dogs, but stay away from sweets like chocolate and caramel. If you notice an addiction to peas in your dog, it may be time to stop feeding them peas, and leave them with dog food until the addiction has passed. As usual, keep a close eye on their appetite and mood, because human food can sometimes work negative consequences into animals.
