Rottweiler approved
Color: Purple
My Rottweiler puppies love these bones. I feel good about letting them play with these and not worry they will break or that they can choke because they are durable and a good size and weight. I like the variety and can put peanut butter on the crevices if I want to give as a treat. Worth the money!

Perfect for the aggressive chewer
Color: Purple
I purchased these because I have a 1-year-old black lab redbone coonhound mix who destroys every toy and Bone. I have gotten him in a short amount of time... These things have outstanded this little guy and he is still enjoying them!
Keeps him occupied and satisfies his chewing for hours!
And he leaves my shoes alone haha

Best for all chewers!
Color: Purple, Color: Purple
I purchased in February and waited until ive had them long enough to make a justified review. I have a very VERY aggressive chewer. He destroys every toy he gets within minutes or a hour. We didnt expect much out of these but why not. Let me tell you... they only have small teeth dents. No cracks, no breaks, no chunks missing, none in the trash, no bleeding gums... nothing. My chewer loves them. First day he just stared at them like they were alien objects but after we played fetch a few times it was on!! Now all three dogs chewer on them. I would say im purchasing again but I dont know when that will be lol I highly recommend to anyone!! Photo is taken today 6/4/26

My pit bull loves them.
Color: Purple
I picked up the Frienhund Tough Dog Toys 3-pack for my large, heavy chewer, and overall I’m pretty impressed. Right out of the box, the toys feel solid and well-made—definitely more durable than your average chew toy. My dog usually destroys new toys within a day or two, but these have held up significantly longer, which is a big win.
They also do a great job of keeping him occupied. The shapes and textures seem to keep his interest, and I’ve noticed less destructive chewing on furniture since introducing these. That alone makes them worth it.
The only reason I’m giving 4 instead of 5 stars is that while they’re very tough, they’re not completely “indestructible” (despite the claim). After a couple of weeks of heavy use, there are some visible wear marks. Still, compared to most other toys we’ve tried, these last much longer.
Overall, a great option for medium to large dogs that are aggressive chewers—durable, engaging, and a solid value for a 3-pack.
