From the CFA Breed Profile: The colorful personality of the Tonkinese make them ideal companions. They will take possession of your lap and shoulder, and they will supervise your activities. They are warm and loving, highly intelligent, with an incredible memory and senses that are akin to radar. They are strong willed, and their humans are wise to use persistent persuasion in training them. They are naturals at inventing and playing games, using favorite toys to play fetch, and delighting in games of tag with each other. Of course hide ‘n seek is a favorite game, which they play with humans as well as other Tonks. They become your “door greeter” and will happily entertain your guests. They have been described by enthusiastic owners as part puppy (following their owner around the house), part monkey (their “acrobatics” are legend!), and can sound like an elephant running through your house when they choose. In short: they quickly take over and run your house and your life! Their affectionate ways are impossible to ignore, and they quickly endear themselves to family and visitors.
If this sounds like your kind of companion then a Tonkinese may be for you.
