Finally an all-purpose toy that doesn’t fall apart!
I thought there wasn’t a toy in the world that could withstand the craziness of our 95 lb German Shepherd, until I found this! It’s great for rolling, tugging, fetching, and chewing, soft enough rubber for his teeth yet so far solid enough to not fall apart. He’s had it for almost a month and I don’t see any rips, holes, or missing pieces. I don’t know if it floats since we use it in the house. And a HUGE bonus: IT DOESN’T SQUEAK. 🥳🥳🥳 We ordered a size Large and it’s a perfect fit. He loves to grab and carry it around when he’s excited, so it’s solid but not too heavy. Will definitely be checking out more toys from this brand. Thank you West Paw!

Durable with limitation
Size: Large, Color: Granny Smith
offers good durability, but our Olde English Bulldogge was able chew an end section nearly off so cut it off and allow him to enjoy the Zogoflex under supervision

The BEST Chew Toy for Big Chewers that Come in Small Packages
Size: X-Small, Color: Granny Smith
The best toy I've found so far. I have a 4 pound toy poodle who is definitively a big chewer. He never rips up his stuffed toys but has worked his way through a huge amount of "tough" chew toys made for toy breeds.
This one is tiers above the rest. Not a single piece is falling off, he LOVES it, and the teeth on rubber sound when he's chewing on it is really quite cute. It's hard, but not too hard, and the perfect fit for his little build. 10/10 I'd absolutely recommend.

Great toy
Size: Large, Color: Teal
2nd one we ordered in two days. Our dog love the first one. She is a big chewer and the toy held up after hours of play and chewing. We wanted a second one to have on hand in case we lost the first one. Seems to hold up great.
