This version of our Quick Release collar has the added benefit that the collar size can be adjusted to fit multiple size dogs in seconds. The leash length is 27 inches from the dogs neck to the handle. The collar size is quickly adjusted from 5 inches and up to 28 inches. This collar does not include a neck pad like the original version of the Tally-Go Collar although a pad can be added if the size adjustments being made are within the measurements of the colllar pad that you would use. If you want a collar pad please order it separately and select desired size and color. The leash color can be spefiied under additional comments: Pick any leash color options listed for our Standard QRCS collars.
