I think anyone would find it useful.
I ordered this for my small dog so we could learn retrieving better. I personally think it is a bit too big for a small dog so we use it as a great storage for treats to take with us or have on table for easy access. It closes really well, treats don't lose the smell and it has a loop attached which is great to keep it on hand or attached to a leash. Great price, I ordered two and one stayed with us while other is used at animal shelter. Thank you!
