My daughter has a small chi/pom that hates just about anybody but her. (Nip Nip Nip-Yap Yap Yap) The grandchildren are old enough to listen but young enough not to care what you tell them.  Long story short this gate is for her bedroom.  The gate has a lock on the top that small hands cannot manuever so therefore they stay out of her room and the little pet door allows the DOG to go in and out with out them messing with him.  I am very happy!
