It's really tough say, for sure, how big she will get...but a guess would be somewhere btwn 5-6 pounds.
What's her name? You should post some piccies of her.
Btw, be very *very* careful and attentive to her bc, technically, she should still be with her Momma at this very young age. Good breeders will generally keep their puppies w/ their Mommas until they are at least 12 weeks old AND 2 pounds in weight. Puppies are very vulnerable little creatures who can go downhill fast if something goes wrong -- so just make sure that if you see any concerning changes, you head right to your vet asap. Don't take her to public places or dog parks etc until all her puppy vaccines are complete. Are you free feeding her right now? If not, you should be feeding her at least 4x a day right now.
