Chihuahuas are excellent pets, but a dog owner must bear in mind that the Chihuahua lifespan is shorter compared to human lifespan. That said it is important that the owner to make sure that his/her Chihuahua has a long and happy life.
You can tell these two have been raised together from babies. There's no stress on the dog's face, like stiffness in the neck or uneven eyebrows. No look to the owner of "help-do you see this?," type of behavior. That leopard is too funny..and onery. lol
