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.

Indestructible m
It’s actually indestructible. I have a black mouth cur who once ripped apart a Kong toy in minutes. Got him this and another ball shaped one for Xmas and 5 months later, there are just some puncture holes, no rips or chunks taken out! They’re in his top 3 favorite toys for sure!

Truly great quality for tough chewers
I seldom leave reviews, but after years of reading endless reviews for different dpg toy products that claim to be "indestructible" but end up being no match for our sweet but genuinely TOUGH chewer pitbull, I never expect much... so was so pleasantly surprised, no, shocked, by the quality of this WoofBite toy. Please note these photos are after about 3 months of use (and you may notice our dog is laying in a sea of other decimated toys that lasted only days, if not hours). Again, not a big reviewer, and I know no two dogs are the same, but if our experience is any indication, we felt we needed to make this recommendation to other bully breed owners out there who, like us, are skeptical of anything out there claiming to be indestructible. While our dog gets so much joy and takes great pride in the art of destruction, the endless revolving door of buying her new toys translates to lots of money spent. It is nice to finally find a new option to add to our very limited list of brands we will buy for her. Good news is, she still really enjoys playing with this toy and she is enjoying the challenge. I can confidently say this has been a GREAT buy for our spoiled little pitbull and we will be scooping up more for her grandparents house, our summer camp, and some backups just in case these ever become unavailable. Thank you!

Very cute, good quality
Style: Lambchop, Size: 10", Style: Lambchop, Size: 10"
Our Two year-old Great Pyrenees rescue loves her Lambchop. She’s fairly gentle with it, but it did accidentally rip so we had replace it since she loves it so much. No fault of the product. The product is very well made, She just got a little rough with it.

Excellent for chewers who like to extract squeekers. It has many.
Style: Lambchop, Size: 10"
This was my dog Clarks favorite toy. When he passed away last year, I saved his played with lamb chop and it sits near his ashes. My current dog Walter loves lamb chop too. I appreciate the squeekers in the all the mitts. It really adds so much to this toy. Great design. Durability will always be an issue with soft fluffy squeeky toys. I buy this knowing that half the fun for my dog is trying to extract all the squeekers.
