Thanks to all for your opinions. Breeder who sold me the puppy is very famous breeder and she is the judge too. Her pedigree is also good.
I could belive that this could change maybe till she stop growing but not later. But breeder said to me that this can change till 18 months????

This is very hard to belive, becouse yorkies stop growing at 7 months.
She did not gave me guarantee that she will be good for shows on paper, she just told me that a lots of times. She said this to me by mail too. She gave me only teeth guarantee.
About pictures, I don`t think you will see anything from pictures, becouse the topline can look good on pictures if I raise her like it looks good. But the fact is that when she moves the topline is not level.
I will put a short video on this forum and this is the only way you will able to see her topline in movement.
