As Chihuahuas, we learn that we need to take care of each other in a pack. And let's be honest, sometimes there are things that we just cannot do on our own. A perfect example of this would be grooming our face. How can we keep it clean? We can't just walk up to a sink on all fours and lather our paws up with soap like you humans do. So we rely on each other to keep our faces looking puppy pretty.
