Non aggressive chewer destroyed in 10 mins
Color: Light Pink, Pattern Name: Roses
Unfortunately this is definitely not for aggressive chewers. We had to throw it away after 10 mins and it was given to a small dog.
She did absolutely love it, but it shouldn't have shredder the toy like she did. The spikes were literally falling off. I don't know if we just got a defective one, but I'm definitely not happy with this purchase.

Depends on the KIND of chew
Color: Red, Pattern Name: Roses
I’ve given this to my fosters and most love it and keep it for a LONG time. Now I have a Pibble who figured out how to pibble tiny bits of plastic instead of just chomping.

Dogs Love!
Color: Real Bacon&Beef
My dogs love these. I originally had ordered one but the 3 dogs kept stealing it from each other so I had to buy more. I purchased 2, 2 packs. Highly recommend if you have some chewers. Great quality for the price. They do seem to last a while as well. Highly recommend.
