My unique sterling silver Australian Shepherd charm is 1/2" tall by about 5/8" wide. It was a challenge to capture the joyful nature of this breed in a charm! And since I have met many Aussie dogs personally, I really wanted to get it right! Funny thing; I have had some customers purchase these to represent their border collies as well. Each charm has a sterling silver spring ring with 2mm opening so it can attach easily to your charm bracelet. Have fun creating an all dog charm bracelet!
