Dog books often describe Chinese Cresteds as very friendly, but this is actually the exception rather than the rule. Yes, he will most likely smile at you when he is naughty, but it’s not quite the same. He is likely to be extremely sensitive and reactive, and has a high social drive that makes him needy. (Expect yours to sleep under the covers with you.) He can get along fine with familiar people, but he is likely to bite strangers unless he has been well socialized and trained to refrain from this impulse.
