Best toy for heavy chewers
Color: Green
My dog is an aggressive chewer and I have trouble finding toys that last longer than 5 minutes before being so destroyed it is no longer safe to let him keep it. He loves this toy and naws on it for hours daily. Yes, it has multiple chew marks, but it is still intact completely. No little pieces have been chewed off. I highly recommend this toy for any dog especially those who destroy every toy in seconds like mine does.

NOT Indestructible and a Nylon Product (NOT A CHEW TOY)
Color: Green, Color: Green
I gave this dog toy 2-stars based on my dog toy rating system (DTRS) for “Bruce” the Green Alligator!
Unfortunately, I didn’t notice in the fine print of the product description on the website that this toy consisted of Nylon. If I noticed that description, I would’ve never purchased this product. Please do your own research on Nylon wrt teeth. I wasn’t impressed with the toy construction out of the box. The nylon head and tail sandwich the rubber body with soft rubber spines on Bruce’s back for easy gripping. This is not an “Indestructible” dog toy.
Safety (1-rating):
1. I was always concerned about my dog’s teeth possibly cracking while he was chewing on Bruce’s Nylon ends. Thankfully, his teeth were fine throughout the use of this toy.
2. The Nylon came off in small pieces after a few hours and continued for the life of the toy; see picture. I never intended for my dog to swallow pieces of Nylon.
3. Bruce’s rubber rear end is where most of the damage occurred, as my dog was tearing off pieces of rubber and spines, which he thankfully passed through his system over a period of 2-3 days after I threw Bruce away; see picture.
4. The chewed-up Nylon ends were very hard, rough, sharp and pointy. There were occasions where I noticed my dog’s gums were bleeding as a result of chewing this toy.
5. Bruce is big enough not to swallow in its entirety, which is why I’m giving this a 1-rating for safety.
6. This is a molded product and not a plush product.
Durability (2-rating):
1. It took my dog 1 to 2-weeks to get the toy in the shape that is shown on the posted photos.
2. The Nylon was immediately being scratched and scraped apart on day-1. Then I noticed pieces of Nylon coming off of Bruce after 3-4 days.
3. The rubber was immediately being punctured with small divots around the body on day-1. I noticed over the next couple of days that my dog was focusing on the rear end and trying to pull the rubber off the Nylon tail.
4. The rubber started coming off more quickly after 1-week, until I removed it all together.
Squeaker (N/A):
1. Bruce has no squeaker.
Fatality (2-rating):
1. Bruce had a longer life than most of my dog’s toys, but then again, I expected this to last much longer as the seller claims it is “Indestructible”, which it is not.
2. I tried filing off some of Bruce’s chewed up Nylon ends to smooth them out for more chew time, but came to my senses and just threw him away for safety concerns only.
In conclusion, “Bruce” the Green Alligator should not be given as a chew toy, but more as a fetch toy, unless you want your dog to digest the Nylon and rubber materials.

This has been a challenge for my extreme chewer! The toy is winning
Color: Green
Indestructible? Not for my pitbull. Except on this toy. She has slowly chewed some of the outer portion on the backside, but it still has a lot of gnawing time left. This is her go-to toy now. she carries it nearly everywhere. She loves it. I am amazed at how well it is holding up. Within minutes, hours or a few days, the other "indestructible" toys I've purchased, never survived as described.
This is a heavy toy! Not for the weak! I cannot stress enough the extreme chewer my dog is. Yet, I can see this toy lasting months. It won't be pretty then but it will most likely still be a favorite chew toy. I'm glad I found this and will be buying more.
FYI's... 1) Chewability-5 stars 2) Softness-1 star, it's solid but chewable, 3) Bounce-0 stars, No bounce, it's heavy!, Playability- 5 stars. My dog plays with it, lets it lay with her when resting. Nearly always within her reach. She sleeps with it! That's love.

My buddy has been chewing on this for an hour!
Color: Green, Color: Green
This dog toy has been a great addition to our dog’s toy collection! My dog can be a pretty aggressive chewer, so I’m always looking for toys that are durable and can actually hold up to daily play. This one has been surprisingly tough and has lasted much longer than many other toys we’ve tried.
The material feels strong and well made, and the design makes it easy for my dog to grip and chew. He loves carrying it around and tossing it during playtime. It’s also great for keeping him busy and helping reduce boredom, especially when he has extra energy to burn.
Another thing I like is the texture of the toy. It seems to help keep my dog engaged, and it’s sturdy enough that I don’t worry about it falling apart right away like some softer toys do. It’s been used for chewing, tugging, and even some fetch around the house, and it’s still holding up really well.
The only small drawback is that I wish it had a squeaker inside. My dog absolutely loves squeaky toys, and I think that would make it even more exciting and keep him interested for longer periods of time.
Overall though, this is a very solid and durable dog toy that’s perfect for dogs that love to chew. If you’re looking for something tough that can help keep your dog entertained and reduce boredom, this is definitely worth try
