Hi Beth,
This is our design. We do have a Mini version of this pattern which is just the Silky Terriers head. The Mini pattern is 90 x 100 stitches. Unfortunately we have not added it to the Everything Cross Stitch website as yet. You can buy it from our website as a download or printed pattern. If you do a google search for mini silky terrier artecy shop you will find it. I could add it here, but it will take a couple of weeks to come through, but if you would me to just let me know.
If we resized this current chart for the whole dog, it will lose alot of detail, you would be best to stitch on a higher count as DancyFrog suggested, you can stitch on any count you like, there will be no distortion it will just make the finished pattern smaller.
Please let me know if you have any further queries.
Thanks and Best Wishes
