Indestructible dog toy
Color: 1PC-Beef-Red, Color: 1PC-Beef-Red
I have an 85 lb Pitbull and he loves to chew on those kind of hard bones but the meat flavor and scent is only in the middle the knobs on the end are just plain nylon and yes it is taking him a long time to get through them but little white fibers keep coming off I find them on the couch and he nibbles and tries to eat it so I believe he's eating the nylon and still has yet to get to where the beef flavor is in the center he doesn't chew from the middle he goes from the end all of his other chew toys he has he has demolished this one not so much I only gave four stars because my dog doesn't like it so much it is a very good sturdy toy though and has a good beefy smell. And a fair price.

Not completely indestructible but definitely long-lasting with plastic bits everywhere
Color: 1PC-Beef-Red
It's destructible it just takes a long time and tons of tiny little plastic pieces everywhere and even in your dog's stomach would not recommend due to wear and tear on dog's teeth and the plastic chips off.

Great Product!!!
Color: 1PC-Beef-Red
This is the first toy my dog has not demolished. I need to buy more just like it just in case something happens to this one. It's worth every bit of the money I spent on it.
