The best bone you can get for pitbulls!
Size: Large (Pack of 1)
Can I give these more than five stars? Please?? They truly deserve more than that! I have bought these bones for the last 2 years for my pitbull mix, who is a very aggressive chewer. Her favorite thing to do is just lay and chew. These bones last FOREVER! She can lay there and chew all day long and they will last her MONTHS! It’s honestly amazing! These are the best bones we’ve ever given her and they are the only ones we’ll buy her! Not only do they last forever, they’re safe and natural too! Best product ever!

Great for aggressive chewers, but small mess
Size: Large (Pack of 1), Size: Large (Pack of 1)
He took it right away! It’s a great size. We’ll see how it holds up ONE MONTH UPDATE: (photo included) He loves it still! Still a bit messy but holding up great and he’s a aggressive chewer 1 WEEK UPDATE (photo update included) The bone is great. He loves it and it’s been holding up great. Our 8 month puppy is a super chewer and 60 lbs. the bone has signs of wear but nothing crazy. I went from 5 stars to 4 stars because whenever he chews the bone, the small tiny pieces of bone/wood go everywhere and they’re sticky/hard and make kind of a mess. But still would get this bone again and highly recommend

Made for aggressive chewers
Size: Small (Pack of 1)
My aggressive chewers are obsessed. This is one of the only chew toys that actually lasts for them. Always have to buy 2 so they each have their own
