I had one puppy one time that had pricked ears...I was bothered by it, but not any longer. This is a fairly frequent occurrence because it is part of being an aussie...they all have different ear breaks, and some not at all! So I've quit beating myself up. I did some research on it and found that it in no way means your dog isn't purebred, or of good quality. Even the people that set the breed standard have said that classifying pricked ears as a fault was a mistake, and a disservice to the breed. However, if you start to see your pups ears go wonky at about teething age, you can glue them down for a few days, and sometimes help them to stay down. It is not harmful to the pup if done correctly. Tear mender is often used....much easier than other glues on the dog. I am just a hobby breeder, but I love and am fascinated by this breed, so I've tried to learn as much as possible about them. I've also learned that there are kind of two categories of aussies..the working dog, and the show dog. Working has the shorter coat, and more often pricked ears. Show has the longer ears, and a fuller thicker coat. Hope this helps, and I'm always eager to learn more! Aussie lover...
