Chihuahuas make terrific pets because of their devotion to a single person. They can be great with other dogs and pets in the home. They need lots of exercise but usually get it running around the house, but a short walk outside is always appreciated and a ride in the car is even better! Chihuahuas have a long lifespan. Some live as long as 18 years. Get acquainted with this dog off leash in our office area. Most dogs will need to run off some energy before they settle down and get acquainted with you.
