Review on 🐶 14-Piece Colorful Adjustable Breakaway Safety Puppy ID Collars Set - Nylon Soft Identification Whelping Litter Collars with Record Keeping Charts by Randall Kelley

It was great for our 9 puppies. But once they started playing and wrestling more, the collar came off too easily. I was at work and came home with a missing collar. I assumed one of my kids accidentally threw it in the pee pads we had. And it turned out that the puppy had swallowed his collar. A week later he threw up in his new home! So my advice plz plz plz don't use them when the puppies get bigger! Obtain a bond in kind that they cannot easily take away. The separation is too easy for the puppies to separate from each other. So infinitely grateful that he threw up on his collar! It could be so bad!
