How long do chihuahuas sleep?

Chihuahuas are known to be big sleepers and can sleep for up to 14-18 hours per day, depending on their age, activity level, and individual personality. Puppies and senior chihuahuas tend to sleep longer, often reaching the higher end of this range. However, some young, highly active adult chihuahuas prefer to spend a bit more time playing and might sleep on the lower end of this scale with around 12-16 hours of daily snoozing.
