Dachshund said “did I hear indestructible‽ Hold my ball”
Color: Grey Bear - Large
My 15lb Dachshund took this toy as a personal challenge. He heard me tell his human brother that it’s indestructible on the inside and said “hold my ball” promptly proceeding to schmurder the textile aspect of this adorable toy. I’d say it took him a total of 23 1/2 minutes to get to the center of this tootsie pop. I’m not even mad tho bc he had no interest in actually ingesting the outer part, and is totally into the inner toy, which is, for him, literally indestructible. It’s solid rubber, has a wild and fun bounce to it on multiple surfaces. Zodiac rates the squeak 10/10. It’s great especially for when I’m on a call or talking to someone in real life and can’t immediately throw said toy or pay complete attention to him. In conclusion: Your dog will probably love it, ((suggest to just keep an eye on them during the schmurder process and make sure you grab all the pieces that come off so none are swallowed)) Depending on your tolerance for squeaker pitch and frequency of squeak, it's a 4/10 in annoyance mostly bc it’s not a long drawn out squeak ((I can not tolerate those toys, they get “lost on top on my fridge” until I get up the courage to throw them out without him seeing)), it’s quick and requires a bit of effort to produce the sound however it’s a very high pitch squeak so it’s all up to your preference. I personally try to buy toys I can tolerate my dog loving on bc when he gets a new toy, it’s his favorite thing for a long time, like, it sleeps on the bed with us for the first month. Hope your fur child loves this as much as mine did. Not sure I’ll do the whole two in one toy thing again only he got through it so fast.

LOVE BARK TOYS!!!
Color: Rad Herring - Medium
I got this toy for my 1yr old Husky/Heeler/(possibly)GSD (approx 42lbs) mix when she came to our home mid/late October of 2025 and the toy lasted until December 3rd 2025 when we had to assist her with opening the fabric to get the toy on the inside. It was a great fun toy for her and the inside toys still is and she loves playing with it. The durability of both the outside and inside toys are great for super chewers! I was glad there was no stuffing because I had gotten her a plush toy once before and she destroyed that immediately. The fabric on this was durable enough to withstand her chewing yet soft enough that it didn’t hurt her teeth. The colors were vibrant and fun for both toys even though wear and tear kinda took some of the fabric color away. I would definitely buy this again once the inside toy is no longer safe for her, especially since the size was perfect for her too.

Good ball for strong chewers
Color: Cheeze Brawl - Large, Color: Cheeze Brawl - Large
My dog loves this ball except the outside fur gets gross really quickly. However, it’s easy to cutoff and underneath is a strong squeaky ball. It’s like two gifts in one. He’s a very heavy chewer and the ball lasts quite a bit.

Take the skin off and get the right size for your dog’s weight!
Color: Panda Bear - Large, Color: Panda Bear - Large
This review is specifically for the panda toy. My dog is a super chewer and will literally go through any normal toy, even the ones labeled for aggressive chewers, within a few hours at most. He’s about to be 10 years old and this is the first time he’s ever had a toy that lasted as long as it has. I wanna mention the outer layer he almost immediately chewed through. To me, it wasn’t worth the fear of him dealing through pieces so I just took the whole “skin” off. However, he’s safely had this for 2 months with no issues and heavy daily chewing until he finally broke it apart. So if you have a super chewer, make sure to get the size appropriate for your dog’s weight and take the “skin” off and you’re left with a quality toy that will stick around! Pictured is a set of 2 new toys of the same variety since he finally chewed through his last batch lol
