Fatty and often contains garlic or chive flavourings. A lick at most.
Short answer
Yes, it's a good idea to teach 'leave it' for foods like cream cheese. Cream cheese is fatty and often contains garlic or onion flavorings, which are toxic to dogs. A small lick might be okay, but preventing access is safest. Keep it stored securely and watch for signs of stomach upset if your dog gets any.
