Gets along with children: Yes Despite not being raised around young children, Nikki is always a perfect gentleman with kids and babies. They can poke, pull, and prod, and he doesn't even make a sound (I think he recognizes just how small they are).
Gets along with other dogs: No Nikki is a typical Chihuahua with a serious Napoleon complex. Dogs, cats, someone riding a bike, trees blowing in the wind...you name it, he will bark about it. He does not try to get into altercations, but he's happiest being an only child.
