The textspeak makes it difficult to understand your question, but I'll try to answer what I think you're asking.

At one year she's still growing, so she won't be a roly-poly at all.

Purina has a fairly simple explanation of what to look for:

Here are 3 simple ways to tell if your dog's diet needs an adjustment.

Rib Check: Place both of your thumbs on your dog's backbone and spread both hands across his rib cage. You want to be able to feel his ribs. Actually feeling your dog is important, as the coat of many dogs will make a visual check difficult.
Profile Check: Examine your dog's profile – it’s best if you are level with your dog. Look for the abdomen to be tucked up behind his rib cage - this is ideal.
Overhead Check: Looking at your dog from overhead, identify whether you can see a waist behind his ribs. Most dogs at a healthy weight should have an hourglass figure.
If you find that your dog's ribs and waistline aren't where they're supposed to be, adjust the amount of food offered accordingly.

Many chihuahua's that we see are all obese. Chihuahua's are suppose to have an hour glass figure. You are suppose to feel the ribs slightly, but not see them. You are suppose to feel the tips of the spine, but not see it.

Small dogs do not eat a lot. Many of these small dogs are force fed over the years to eat more than what they need and become obese.
