Just buy it!!!!
Color: Blue Shark, Size: Medium, Color: Blue Shark, Size: Medium
5 stars so far! My beefy boy is obsessed with this toy. He’s a TOUGH chewer. It fits perfectly in his mouth and it’s definitely tough! Feels thick & sturdy, has no weird smell. He loves the squeaker and he’s been (trying) to tear it up non stop since I gave it to him! Lol. He wore himself out. Definitely ordering more. Love the different animals !

Durable and fun toy
Color: Blue Shark, Size: Medium
My granddog really likes this toy. He is a pit bull mix. The middle is where the squeaker is. Toy is hard plastic and he chewed on it a long time. No damage to toy! The only reason I gave it a 4 and not a 5 is how loud it is bouncing on wood floors. The toy I do recommend. Good size and bright blue color fish.

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.
