Stitching isn't an option(though I'm hoping to offer it in the future), but I talked to some people who made products with rivets, and did a lot of testing before starting to sell them. I stand behind my products so I am certainly willing to replace/refund cost of products that fail under reasonable circumstances. (not to be used as tie outs, not chew-proof, etc.) Thankfully, for the many months I've been using them and selling them, I've yet to have a problem!
Wanted to bump up this thread to say how much we love our Fraggle Rock collars. Jackson's been wearing his double layer lime green/orange one all summer, 5/8" width, since he's pretty much in the pool all summer.
I wanted a bit wider and plain orange one as well so I recently got his 3/4" width orange biothane too and we just love it.
