The collars are such high quality as well, they are really well made, and you can choose the buckles/style.
This guitar one is a martingale.
I got him a nautical one too, and the girl who makes them is lovely and super easy to deal with.
The matching leash for the nautical one is gorgeous too.
I will snap photos when I can.
As for Flip, he's still pretty 'puppy' all around, but he is extremely muscular, so he should be ok in the short short clip.
