Good luck in getting mad at this cute puppy in a cup picture. Teacup Maltese puppies are some of the cutest dogs, and only grow to be an average of 3 lbs. Pleasantly sitting inside a coffee cup, this cute puppy wrote the聽definition of what puppy dog eyes look like. Maltese puppies on the other hand grow to be slightly larger, around 4-7 lbs. Cutest paw has the best puppy pictures!
