Gypsy is so cute in her pics...as far as the weight gain....there I can't help you.  In 5 months Izzy only gained about 5 ounces.

   She's 9 mos now and only 2.6.  She gets fed 2x day - and very limited snacks - only Yorkie Yummies as night before she goes to bed and maybe on the weekends she will get Yummies twice.  She gets no people food.   
Hope that helps a little.
