Think outside the sizing chart!
This review updates my experience with ID collars. My dog has a 16-inch neck, so I ordered a medium-sized collar after looking at the size chart. When I received the collar, I found that when the collar was adjusted to the correct size, the collar length adjustment slider obscured the 2-digit phone number ID; because I bought the ID collar mainly for easy identification, so I found it unacceptable. I corrected the visibility problem, cut the collar ribbon on the slider, and shortened the total length of the ribbon by about 3 ". Reassemble the collar and adjust the collar to the correct size. The slider now does not matter and provides an unimpeded view of the ID. I was satisfied until I realized that since I had to cut my collar short anyway, I could / should order a large size instead of a medium size. I would have a 1 "wide collar instead of 3", with larger buttons, belt accessory rings, and ID letters / numbers. This is due to my perfectionism: I decided to spend another $18.95 and ordered a second large collar. I expected to have to shorten this one because I made it medium size; to my surprise, this was the focus of this comment, and I found that by adjusting the slider until it touched the belt ring (beyond the intention of the collar manufacturer), I was able to shorten the collar without having to cut the belt, beyond the size chart indicated, and achieved a perfect fit and unobstructed ID. Bottom l. No, no.
