Special consideration must be taken in keeping a chihuahua in the home due to their tiny/small size. Every chi should have their own exercise pen (example on supplies page) to stay in when they are alone or unsupervised in the home to avoid getting into danger.
Chis are inquisitive, and will pick up objects then chew or swallow them which can cause serious health problems. It is well worth the small investment into a sturdy ex pen to keep your little darling safe while you are away.
Basic training
Although chihuahuas are small dogs, and usually owners do let their chis get away with a lot of misbehavior that is not tolerated from bigger dogs.
A chihuahua is capable of learning and a well-trained, well-behaved and well-adjusted chi is always a joy to live with.
