Review on 🐶 Optimized Dog Training Equipment - Bonus: Puller Plus - Giant Medium K9 Large Dog Training Tool - Boost Your Dog's Real Physical and Emotional Load - Premium Dog Supplies by Michael Henderson

These things are damn cool! Hell durable! I have a labrador and an ugly 40 lb puppy terrier. They chase these things all day, every day. The rings are all covered in teeth marks, dirt and dog saliva but my goodness these things are still intact and roll great. Been using them for about 5 months and they still work. As for the material, I was skeptical at first. This is a type of foam that's pretty easy to pierce with dog teeth, but they don't destroy it. The gnarlier he gets from the tooth marks, the more he magically transforms to keep his shape. That is nonsense! I don't leave them for the dogs to play on their own as if they just sit and chew on them they can probably destroy it. No chew toys. I would say I would definitely buy again but I may never have to!
