I've used mostly Gooby harnesses on Nilla. They're pretty adjustable -- she wore a small through her first few months with me, and now she's been in, and has stayed in, a medium. I don't know if she was ever small enough for me to merit getting an extra small because she stayed inside until she had all of her puppy shots, and she's a teapot girl now so she grew pretty quickly! ^^ My in law's adopted a Yorkiepoo who was super scrawny when they got her, and the small has worked with her up until recently (she can still fit into it, but she's in between small and medium now because of a growing belly).

I highly recommend the Gooby harnesses since they're really good for dogs who pull, and we know that puppies aren't exactly fond of the idea of being leashed and lead around! Lol!

Good luck! ^^
