I love this line - I have two sets of collars and leashes so far. My 9 month old Golden is still growing and I appreciate the weight and extra sturdiness as she's still in training and she pulls sometimes. I started her with the Front Range line (which is also great), but the clasp on this and the matching leash are a little more heavyweight. PLEASE make more girly options and fun colours (pinks, salmon, orange, cream, magenta, violet etc). The only thing I wish I could change on this would be to have the pattern on both sides of the leash, as it spins around and sometimes you see more of the flat blue side.
