Chihuahuas are known for their affectionate nature and there are certain things that they love which bring them joy. Some of these include tummy rubbing sessions, sleeping with their owners, cuddling, and receiving their owner's undivided attention. They also enjoy treasure hunts with treats, watching cartoons on TV, and hanging out near windows to observe the world outside. Engaging and interactive toys, chasing balls, and rewards during grooming sessions are also things that make them happy. Calming music and a clear window view are additional sources of happiness for these adorable puppies.
