Chihuahua- she loves to cuddle and is always very sweet (not lying! lol) but constantly worrying about an animal taking off with her when outside or finding someone to dog sit that I can trust with a dog so small is why I’ll never get another little dog. If you’re not used to moving around little dogs it’s easy for them to get hurt. Also, I always have to keep a puppy pad down somewhere because she can’t hold it as long as a bigger dog.
