At one 1 I usually start to see my dogs filling out more, not really up. However, you said she had a rough puppyhood with Giardia. Sometimes certain medications and illnesses can be so taxing on the body, growth is unfortunately stunted. So many she's just putting on some normal growth now, where before she just didn't. Storm gained about the same between 8-9months through just a few weeks ago at almost 1.5years. It's normal for them to grow for the first 2 years, but the dramatic changes usually end at 1-1.5. She sounds about right.... (depending on how long ago the year mark was). Storm is just about the same size as Rogue.
