Oliver is a teacup chihuahua! They do not grow they are very cute and small. He is black and white. Just turned 2 years old in March. He comes with his passport/ imminuzation card. I am selling because he was a companionship for my autistic son, but they aren’t getting along well. My son is a bit too rough. If needed I can add his dog cage(where he sleeps while open) dog leash, harness, etc for an extra $50. $250 total. Great price! We payed $550 for him in December.
