Quality material and looks good.
Color: Green
Great chew toy for medium to large dogs. Seems to hold up to their chewing. Very heavy and could damage floors or furniture if your dog happens to throw it in the air.

Alligator chew toy
Color: purple, Color: purple
Excellent for heavy duty chewing. Good size for medium size (15-25lbs.).
An instant hit with my dog. Very durable. I feel it is safe for my dog to have unsupervised.
I rate this HIGHLY RECOMMEND.

Held Up Better Than Most for My Aggressive Chewer
Color: purple, Color: purple
I have to give the Fuufome Dog Chew Toy for Aggressive Chewers a solid 3 out of 5 stars.
I have a very high-energy Lab mix named Boone who is an extremely aggressive chewer. Finding toys that last in our house is nearly impossible. This is actually his second toy like this - the first one is currently in my yard in three different pieces.
While I don’t believe this toy was advertised as indestructible, I still hoped it would fully survive Boone’s chewing. Some parts have held up well, which is more than I can say for many other toys we’ve tried. However, he was still able to do some noticeable damage to the rubber portion after consistent use.
To be fair, it did last longer than most toys we’ve purchased, which says a lot considering how tough Boone is on his things. For moderate chewers, I think this would hold up quite well. For truly aggressive chewers like mine, it’s tougher than average but still may show wear over time.

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.
