Highly recommended for any owner of a "Super Chewer."
Rating: ⭐⭐⭐⭐⭐ (5/5)
Title: Finally, toys that can actually withstand my Labrador’s jaws!
If you own a "power chewer," you know the struggle: you bring home a new toy, and within ten minutes, it’s shredded into a thousand pieces of foam and plastic. After going through countless toys that promised durability but failed within a day, I decided to give the WOWBALA 2-Pack Indestructible Dog Toys a try—and I am genuinely impressed.
The Durability Factor
The biggest selling point here is the material. These are made from high-density, food-grade nylon, and you can feel the quality the moment you take them out of the package. They are solid, heavy-duty, and have held up perfectly against my Lab’s relentless chewing. Even after a week of heavy use, there are only minor surface marks where his teeth have made contact, rather than the dangerous chunks that usually break off other toys.
Design & Engagement
The pack comes with two different shapes—a stick and a ring—which is a great variety. The curved, ergonomic design of the stick makes it very easy for my dog to hold between his paws while he chews, and the textured surface seems to really hit the spot for him. I’ve also noticed that it helps keep his breath fresh and his gums healthy since the texture acts almost like a toothbrush while he plays.
The "Milky" Scent
One thing I was initially skeptical about was the "milky scent." I wondered if it would be overpowering, but it’s actually quite subtle. It was strong enough to immediately pique my dog’s curiosity right out of the box, but it doesn't leave a weird smell on my carpet or hands. It’s clearly effective, as he keeps coming back to these toys even when he has others scattered around the room.
Peace of Mind
Beyond just being tough, I appreciate that they are non-toxic and dishwasher safe. After a long day of outdoor play in the mud, being able to just toss these into the dishwasher and have them come out clean and sanitized is a huge convenience.
Final Verdict
If you have a medium to large breed dog that loves to destroy everything in sight, these toys are well worth the $15.99 investment. It’s rare to find a product that lives up to the "indestructible" label, but these truly do. They’ve been a lifesaver for keeping my dog occupied while I’m working from home, and it’s a relief not having to play "clean up the debris" every evening.
Pros:
Extremely durable high-density nylon.
Great value (2-pack).
Easy to clean (dishwasher safe).
Engaging design for teething, training, and boredom relief.
Safe and non-toxic.
Cons:
Because they are hard nylon, be careful using them indoors on hardwood floors—they can be a bit noisy when dropped!
Highly recommended for any owner of a "Super Chewer."

These are way better than I expected and hold up to our aggressive chewer spectacularly!
I got these specifically for our newest pup (an 8 month old lab/pitbull mix--she's a big puppy, lol) who is obsessed with toys and chewing. She has a tendency to go through her toys quick, both chew toys and soft ones, so I wanted something that would last a bit longer for her because I can tell she gets a bit sad when we have to trash one that's hit its lifespan. So far, these have been a big hit! They're the perfect size for her to pick up, the chicken claw-style texture is great for both keeping her interested and giving her some grabbing options, and they do seem to hold up to their claim of being made for aggressive chewers! There's obviously some wear, but it looks like expected chew toy wear; no claws have snapped off, and her chew marks look relatively minimal compared to what she's done to other chews. I also appreciate that these came in a two pack; we have a smaller dog, and while these are technically big for him, he enjoys having one to play with and chew on as well. These have been a pleasant surprise and I actually think I'll come back to buy them again whenever they're spent! Definitely a worthy purchase!

Creepy chicken feet, made for big dogs and Frenchie approved
These chew toys have been a hit with our dogs.
We have three French Bulldogs who firmly believe they are ferocious wolf-sized predators, and these toys have held up surprisingly well to their daily chewing sessions.
The chicken foot shape keeps them interested, and the durable nylon construction has stood up to much more abuse than many other toys we've tried.
The toys are easy for the dogs to grip and carry around, and I appreciate that they're simple to clean when they inevitably get covered in slobber. They've also helped keep the dogs occupied and redirected some of that endless Frenchie energy away from furniture and other household items.
Overall, these have proven to be durable, entertaining chew toys that are Frenchie-approved.
Although, based on the dramatic growling and victorious prancing around the house, you'd think they personally hunted and defeated a giant prehistoric chicken

Creepy Little Chicken Feet… But My Dog Is Obsessed
Creepy Little Chicken Feet… But My Dog Is Obsessed
I am not even going to lie, when I first opened these WOWBALA dog toys, I had to pause for a second because why do they look like actual little chicken feet? 😂 They are definitely a little creepy at first glance, but apparently my dog does not share my human judgment because she went absolutely crazy over them.
These come as a 2-pack, and they have a bacon scent that is very much not for me, but clearly made perfect sense to her. The second she got one, it became her new prized possession. She carried it around, chewed on it nonstop, and I am pretty sure she even tried to hide it somewhere in the backyard like she had discovered buried treasure.
What impressed me most is how well these hold up. My dog is not gentle with toys at all. She chews like she has a full-time demolition job, and somehow these still look basically new from a normal glance. Up close, yes, you can see where she has been working on it, but it has not broken apart, shredded, or left those annoying little toy pieces all over the floor. If you have ever bought a chew toy that turns into confetti within 20 minutes, you already know why that matters.
The nylon feels solid and heavy-duty, and I like that it is made with safe, non-toxic material since this is something she keeps in her mouth for long periods of time. It also keeps her busy, which is a huge win because bored dogs will find their own entertainment, and usually it is something expensive or inconvenient.
So yes, the chicken feet design is a little weird. Yes, the bacon smell is definitely for the dog and not the humans. But my dog is obsessed, it keeps her entertained, and it survives her chewing like a champ. That makes this a solid win in my house.
