I used to be able to search collars by size but I noticed today that that is no longer an option. Since most of your collars are for small-medium dogs, this makes it far too time-consuming to search for fitted products for my Rottweiler. I also wish I had the option to go ahead and pay for products that are temporarily out of stock and have them ship when they are in stock, so that I can utilize coupon codes as they come in and therefore get the discounted price.
