Best known for its active  and lively nature, the Prague Ratter is a spunky breed that is full of  original character. These tiny dogs thrive on strong and dependable  relationships with humans, love to receive affection and play the role  of lap dog during down time. This breed is highly intelligent and  generally responds well to basic training and commands. As a pet, the  Prague Ratter is obedient, loyal, loving, and very affectionate. The  Prague Ratter adapts well to full-time indoor and apartment living, yet  still enjoys spending time outdoors, playing games such as fetch, and  taking long and leisurely walks. They are also known to be a very quiet  dog unlike many other small dogs who tend to be very "yappy". Like any  small dog one should be wary of allowing them to develop Small Dog  Syndrome as they can become aggressive if they are allowed to become  dominant over their owners.Ideal height is 20 cm to 23 cm.
