alright Tex, dogs are animals too, just like coyotes chasing is a natural instinct.
A well trained and cared for dog will not chase. My two dogs are Australian shepherds and chasing is their job. However, they do not, and will not chase until given the command to get to work.
Dogs that chase are a nuisance and a danger. Have a 100 lb dog chase your kid on his bike and nock him down. See how understanding you are then.
