Hi, Brittany! Peanut sounds adorable! This is a great place to meet other chihuahua owners and ask any questions you have.
I've had two Chihuahuas littles before, one 2 pounds 1 oz., one 2 pounds 11 oz., and they were both still within the breed guidelines. Nowadays, my littlest is Cocoa, 5 pounds, my biggest two are Cowboy, 9 pounds, he needs to lose some weight, but he's handicapped and walking isn't an option, and Babushka, 10 pounds, she's a little butterball. She's my daughter with Down syndrome's dog and she sneaks her treats.
