My Artie, is 1 year and 2 months old I still give him Nutri-cal when ever he will eat it? Daily....some days he eats it some days he won't? Yorkies will play and play until they drop. One minute he will run a golf course and the next minute he will be sleeping. Some days he eats his kibble, one day he won't eat anything. You never know the Nutri-cal is my Insurance and I could'nt live without it! I would get her checked/tested by the Vet. the smaller tea-cups are alot higher risk, they are more fragile & delicate! The first year is the hardest and most stressful, I was a nervous wreck. But now I don't worry anymore, just the normal stuff. Good Luck
