i just got my yorkie the day before xmas and for the last two days when she eats in the morning she throws up....she doesnt have diarehha(sp?) and when she eats in the evening /night she is good. i talked to two vets. one said she might have kennel cough. the other said she is eating too quickly when she wakes up becuase she is excited she has food, and that her morning food amount is too much that she is being fed.also i am looking to get insurace through petsmart vet they have in the stores .my main questions are

1)what do you think is she eating to much and too fast?
2)how much should a 10week old yorkie be eating a day in terms of measuring cups?
3) whats the best insurance and is it really worth it?

thanks .
