You might also just take her to your vet for a check up......maybe she is just a little over weight; which can be a big problem for little dogs. Lucky, one of my males, is just a little guy and his weight got up to 8 lbs last year. Our vet was a bit concerned having all that weight on his little legs & knees, as was I. But I am happy to say that he is now down in the 6 1/2-7 lb range and we can see the fruits of our labor. He is much more active than he was a year ago.
