I can really identify with your story! Before getting shelties I had 2 mini dachshunds who both lived to about 14. I was broken hearted when they died and waited a couple of years before getting another dog. I wanted to get a different breed because I didn't want to keep comparing the new puppy to my doxies. I decided on a sheltie because everyone I knew who had shelties talked about how wonderful they are - smart, affectionate, and cute.
I did a lot of research and found a wonderful breeder. I really wanted a sable but during my first visit to the litter a little blue merle boy crawled into my lap and my heart so that decided that. Shelties are a lot like potato chips, so I also got a sable and a couple of years later another blue merle, all males. My first blue boy died a few years ago. The house seemed empty with just 2 so I decided to get another. I REALLY wanted another boy - a tri-color. I never had a tri-color before and they are so beautiful. I called the breeder and learned that one of her dogs was expecting a litter in a few months. She shows shelties and is an AKC judge - she doesn't breed her dogs very often.
When the litter was born they were all female - and all sable. Not what I wanted, but this breeder has such wonderful dogs I couldn't pass up a visit. That's all it took. A little girl, the runt of the litter, picked me and that was the end of that. I can't describe how much I love her. She has her two brothers wrapped around her finger (so to speak). I don't think we pick the dog - I think it picks us.
I've been a member of SN for a while and have found a lot of good advice here. I lurk more than post - but I love reading the stories and seeing all the pictures. Welcome!
