- Teacup Chihuahua
7 week old female teacup chihuahua. She's great with other dogs and kids. My 19 month old son is too young to have a puppy right now he's just a little too rough and she's just a little too small. I will include Nutro puppy food and a collar. She will go to the bathroom outside as long as you are proactive and take her out often. She's really a fun cute dog.
