Sorry you had to remove the photos due to some unpleasant (or worse) people. I know there are many trials in being a responsible breeder when it is a trend nowadays to use the word "breeder" as a negative no matter what the context. I commend you in your exemplary efforts on behalf of the breed you love. The situation has become quite bad here in my city; some of us in our dog training club have made T-shirts with the words: "No my dog is not a rescue, she was planned!"
I came to this thread looking for the pictures of beautiful Katie progressing from puppyhood to adult. I am amazed how she never looked awkward. I am currently raising a Sheltie pup who is from an exciting breeding, parents both champions, grandparents and further back have many ROMs and BISS, tested for just about everything. Yet, at one point there she looked like some scruffy, half-coyote stray - at that point you just hope that what you saw at eight weeks comes back someday! LOL At 7 months, she is starting to come together again and I hope we do well at our first puppy match in a couple weeks. I am a bit jealous that with Katie you never had any doubt - and with good reason, of course!
Although in truth my Sheltie is first a pet, second my up-and-coming agility dog, and only lastly a show dog. Do you have any other plans for Katie other than the breed ring? I know you do carting with one of your boys. Well-rounded dogs of any breed are such a joy, aren't they?
