TRULY INDESTRUCTIBLE!!!
Color: Blue Shark, Size: Medium, Color: Blue Shark, Size: Medium
This toy is truly indestructible. I have purchased several toys over the past few months, all have been detroyed except for this one. It may not look as pretty now but it is still intact and still squeaks. I highly recommend for anyone with truly aggressive chewers.

Make sure you get this brand. The look alikes are trash!
Very durable and fun! My Pitbull chews on this constantly and loves to have treats or peanut butter, put in the bottom of it as an extra treat. A friend of mine bought a similar looking toy that was destroyed by her pitbull in moments. This one is better quality and has stood the test of this power chewer. The rubber is very thick and he chews it constantly but it stays in tact. It is soft enough to squeak if he gets a hold of it just right, but that’s the rare treat. The size is perfect for my 80 pound boy. I am also able to throw these toys in his pool for him to dive for them. Definitely in great value for the price.

Indestructible, but maybe too much?
Color: Orange, Size: Medium
Not too enticing for my dog, but, it is definitely indestructible! He chews on it every so often, but less than I had expected. I think the material is so rock hard that it offers little incentive for him to chew on it.

Best I've Tried
Color: Blue Shark, Size: Medium
With my pitty pup, there's no such thing as an indestructible toy, but this has been the most impressive so far. It's lasted days vs the typical minutes his new toys survive. It has a squeaker, but no fluff, and this has been great. He's been trying to get at if for a long time with no success! He has tore thru the rubber portion, but there's still plenty of play left in this toy. The 3 different textures keep him interested vs the hard material toys he rejects or chews on them too long and I worry about tooth wear. Definitely buying more.
