I bought this collar and matching leash in an aqua collar with gold and white/clear stones for my 20-pound white and tan Bichon Shih-tzu mix. It fits her neck perfectly and the color is gorgeous on her! We go hiking a lot and she is always getting wet, dirty and muddy so I was looking for something durable but with a little glam for the times she is clean and fluffy. This is it. So well made and looks fantastic. Highly recommend!
