Although the breed standard is between 4-7 lbs, Yorkies come in all sizes. So you could possibly have rescued a giant Yorkie
Your pup may also be mixed with another, larger breed.
You have to resize photos so they can upload. You can use any free online photo editor, like
picmonkey. Go to "edit a photo". After you open your photo, you'll see the option to resize in the left sidebar. If you put 600 in the first box (width) & leave the 2nd box (height) blank, it should make the pic small enough to upload. If not, try 500, or a smaller number.
Can't wait to see pics of your big boy
