I reccomend these collars because they are built extremely well and they have a wide variety of beautiful designs. Easy on and off. Just click and go I own multiple designs. I haven't encountered any issues with them since purchasing years ago.
Dog Collars and Leashes - Buckle-Down
Cat or dog these keep my furry pup busy. He loves some frozen peanut butter and frozen fruit mashed into his kong. It keeps him busy and engaged in solo play when I am busy, which is a huge plus.
