Chinese Cresteds are much more laid back in personality, so I have not dealt with the kind of puppy antics I have with Lady (tri) now. My Crested puppies don't really chew and always follow me around. Lady chews on everything and runs behind the couch to hide. She has started barking at me also. She also plays with her food. She will throw each piece in the air and pounce on it. It is so cute.
