SodaPup Unstoppables solve three separate challenges. If you use treat dispensers for enrichment you know how messy it can be. Our stoppers/stands solve this problem. If your dog chews nylon toys, you know that you throw most of the used toys away. Our chewers/knuckles eliminate this waste. Some dogs can solve their treat dispenser food puzzles too quickly. Our connectors extend play/enrichment time by connecting multiple toys together.
