I have only seen blue Merle's in pictures; I was at the grocery store with Sandstorm and an older gentleman pulled over in his car to show us his sheltie. I FELL IN LOVE! This sweet 15" girl had blue eyes, absolutely beautiful! I don't often see shelties, and this little blue one was adorable. I brought Sandstorm over to see her, what a difference! Sandstorm looks like a male, and is just about 20", 37 pounds. This man gave me his phone number, as I wanted to know where they got this little blue girl. We are planning on getting a puppy in late spring, early summer, I know there is a breeder in Massachusetts who only breeds blue Merle's. I didn't know if I would like the blue eyes but I do! Sandstorm is a very handsome sable and I would be happy with another one, but I would like a little one.
