Welcome, Crystal & Cashmere! What a cutie ... she looks about the same size as our Toto when we first brought her home! I miss that age ... she is 18 months now and such a prissy little lady! She only gets 1/4 cup total food per day and about 1 heaping tablespoon of the Royal Canin Yorkshire 28 dry food [she usually doesn't eat all the dry]. I allowed her to get overweight so now she is strictly on her dog food!
Couldn't tell from the pics, but since Cashmere is from Brazil ... does she still have her tail? I know there are some countries that do not allow them to be docked. Yorkies are precious ... tail or no tail!!
BTW our vet has us give Toto 2cc NutriCal per to make sure that she gets her vitamins, etc. since she is such a picky eater. We had to give it [I believe 1/2cc] three times a day when she was younger. We have only had one episode of a "sugar drop" since we have had her and it was brief. Hope you can find a vet that is knowledgable in the treatment of these little babies. We have all found that there are some out there who don't have a clue!
