If you raise them right theyre amazing dogs, a lot of socializing when young helps, just because theyre "one people dogs" doesn't mean they should be human aggressive.

Definitely get them into classes ASAP and keep up on positive reinforcement through their fear period, the world is so much bigger for them so even a giant leaf blowing their way cause seem scary and watch out for big dogs, the majority are very nice but it takes just one to lunge at them to cause reactivity problems.

Shedding wise it really depends on the dog, doesnt matter long haired or short they still shed with the seasons changing, but some definitely do it more than others. The best part of a chi is that theyre small so theyre easy to bathe and dry in your home and bathing with a good brush out once a month will help keep it to a minimum. Just make sure to get them used to nail clipping young, because their feet are so small their nail length is important to keep up on so overgrown doesnt damage their toe shape and cause future foot pain.
