A friend of mine wanted to see a picture of a large coffee book I have. I measured the book and it is exactly 24 inches high. As you can see, Nikki is longer than the two foot long book. I saw an eight year old female Cairn today and she looked like she could easily stead on Nikki's back without losing her balance. It's interesting to see how back and leg length differ between dogs. Nikki is my "terrier tank": he's solid as a rock and he weighs just a little under thirty pounds. His fur is silky feeling compared to the other cairn's. He may be different from the AKC breed standard, but he's perfect in my book.
