Actually indestructible!
Style: Two pack
I am always leery of items marked indestructible because my 100+ lb. dog chews through anything I buy him. But not this. It's solid plastic that he LOVES to chew on. And I love that there are 2 of them so he can have them in alternative places to play with. The shape and texture seems to entice him and keep him occupied for a few minutes, which is a blessing!

EDIT: *NOT* great for aggressive chewers!!! ☹️
Style: Two pack, Style: Two pack
UPDATE (previous 5⭐️): Yep. Things changed!! I take it alllll back!😩🤦🏼‍♀️ Here we are, just shy of a month and they’re both toast!!! The pics might not look like a big deal, but we tossed the orange one after finding the chewed off bits in his poop. The only reason I was able to take a pic of this blue one is because we couldn’t find it until now. However, the orange one looked the same when we tossed it, so I’m sure we’ll be finding blue bits in his poop. Not a fan of ANY chew toy he can actually end up eating!! I have PTSD from our last fur baby that suddenly decided he liked to swallow socks @ 11yo & ended up needing emergency surgery to the tune of ~$5K!🥴 These are crazy!! They’re super hard plastic, almost like glass. I wasn’t expecting that! My hubs was joking they’re for seggy time, not dogs! 🫣😂 We got a puppy in April that is an aggressive chewer. We’ve both had dogs most of our lives, but this aggressive chewing is new to both of us. Lil dude has chewed through a ton of other toys advertised for aggressive chewers- a few within just hours!! It’s wild!! We’re not used to it, but he loves his toys, so we keep trying to get him ones that will last! 😅 We only got this 2-pk yesterday morning, but he’s been obsessed & so far, so good! With how hard they are, I’m feeling very confident they’ll last longer than any other toy we’ve bought him!! I will update if anything changes!
