Dogs are like people when it comes to dairy. Some can digest it, some can’t, and overall it isn’t necessary. It really depends on the lactose content because most dogs are lactose intolerant. Something like whipped cream has 4 times less lactose than actual milk, same with cheese. Even ice cream has two times less lactose than milk. So it is all about moderation and if your dog can handle lactose. A puppuccino will be safe for a majority of dogs.
