The Chihuahua ( (listen); Spanish: chihuahueño) is the smallest breed of dog, and is named after the Mexican state of Chihuahua. Some Chihuahuas may present separation anxiety as a result of being so close and loyal to their owners. This is a fairly common cause behind any pacing, excessive salivating, destructive chewing, or barking, howling, or whining in dogs. Many treatments and tips can help prevent separation anxiety in dogs.
