Questions people ask
Is a Kai Ken good with kids?
With care. Kai Kens generally do well with older children who already know how to behave around a dog; with toddlers, supervise every interaction and give the animal somewhere it can retreat to.
Is a Kai Ken good with cats?
It can work, with management. Introduce them gradually, feed them apart, and make sure the cat has vertical space the dog cannot reach. Plan to manage it rather than assume it.
How much exercise does a Kai Ken need?
An hour or more of proper exercise every day.
Can a Kai Ken handle hot weather?
About average — use normal hot-day sense.
