I have a lot of people who like the Velcro ends on collars, but for real active dogs who roll and rub around a lot, they were working the Velcro ends loose. So it was working good on some and not so good on others, so I wanted to come up with something to fix this deficiency.
What I came up with is a 2" wide ELASTIC keeper that slides over collar and where ever end of collar is when it buckles, end can be tucked/secured under elastic keeper.

These Elastic Keepers will fit ANY 2" wide Collar!!!
