adjective
responsive
rih-SPAHN-siv/rɪˈspɑːnsɪv/
Quick to react or adapt appropriately to a stimulus or need.
The responsive server promptly attends to the customer's request.

Etymology
The combination of “back” and “pledge” underlies a verb meaning to answer. Responsive first meant making an answer, then broadened to reacting readily to an influence or action—not necessarily with words.
In context
the dog is is responsive the dog is compliant and the dog is quick that's what we want in him
