A Dog in your coffee cup can literally mean you will get a dog, but it can also mean you will have more friendships in your life. If you see a big dog in your coffee cup it can mean you will have protection, including spiritual protection, in your life. Perhaps you need to ‘guard’ your life more and take action to safeguard your lifestyle and assets. A guard dog in your coffee cup can mean you must look into having the right insurance as well as safety features in your home, perhaps even getting an actual guard dog.
