Great choice for heavy chewers
Perfect for dogs that chew hard! Ours shred comparable toys at every turn, but this has held up beautifully. We’ve had it for a few months and it’s got minor wear and tear, but it is easy for them to play with, hardy, and worth every penny.

Durable, Fun, soft enough to not break teeth
Finally found a quality toy that our 75lb Black Mouth Cur hasn't destroyed in 5 minutes! In fact it's been a few months now. There are teeth marks, but she hasn't been able to take a chunk out of it yet. It even has some bounce to it when you toss it. And she finds it fun.
Veterinary dentists recommend toys that are soft enough that you can leave a fingernail print in for toys that are less likely to break teeth, unlike bones and antlers. This is that toy! (My other dog broke both of her upper 3 rooted premolars on a Nylabone - healthy roots but the slab fracture exposed the pulp and had to be removed. Healthy roots are more difficult to remove. Dentists say those and antlers are money makers. 😭)

Great toy for big chewers!
Have only had 3 days but my boy has been trying to destroy it and it’s holding up really well! Normally his toys would have been destroyed in 24 hours or less, including Kong and other brands advertised as tough!

Durability is no joke!
Excellent product! Our GSD puppy chewed it for the past 10 months and she is a pretty strong chewer. Only now did she manage to get a couple small pieces off of it, and WoofBite was quick to provide our one-time replacement. Great customer service! Will purchase more of their products and highly recommend!

So far so good
Had this for almost a month and no chunks have been chewed off yet. I have a lab who prefers chewing over pulling or retrieving type toys. She's destroyed everything we've given her --sometimes within minutes. She loves Wubbas but she chews them to bits immediately. Other toys get chunks or small pieces chewed off and we wind up throwing them away. This has lasted well. Full disclosure, we only pull out toys at the end of the day for just a couple of hours, and we are within sight of her the whole time, that's why 4 stars. But so far to our surprise this has held up very well.
