This collar is something I did not know I have been needing. My dog recently was trained on an e-collar, and I was told about the Fi collar from a friend who swears by it and has one for her each of her dogs in her pack. My kiddo was having a Fi collar, her regular flat collar, her e-collar and then her prong all on a walk and it felt like too much. I have been buying goodies from Kaylynne for years and have loved her long lines and bandanas for my pup. This was amazing and she got back to me about sizing in great time. My dog has a skinny neck and it measured right at 13.5. When I received it in the mail, I thought it would be too small for her neck size, but the extra pack of screws helps with some extra length that she ended up having with her collar. I also purchased a pack of 3 tag holders, and that was great to limit the number of collars she wears overall. I also purchased the e-collar remote strap and it came with a loop that you can un-snap which is wonderful for adding it to a bag or a fanny pack if we are on a walk/hike. I love the forest green color and just everything about Hoot & Co. It also is great that the straps are biothane so she can get as wet or muddy as she pleases and it still looks amazing after being wiped down. The wait for the items is well worth it, and makes everything that much better knowing I am supporting a Woman owned business and a small business based out of Colorado. Highly recommend all of the products!!
