Bully proof?!
Size: 5 in
We have the cutest little pit/lab mix who destroys stuffed toys in about two seconds flat. It’s always a HUNT to find toys he won’t instantly shred. This brand has some of the best! They were in FiveBelow for a while and it was the only brand that stood up to him initially. He finally got through the first only after MONTHS so we bought a few back ups and they’re still going strong months later!
They’re also not super heavy so these end up being the toys we play fetch with most often! 100% will be buying more in this line in the future!

Great Option

When this chew arrived, it immediately became a favorite. It seems sturdy and is soft enough to be dental friendly.

Love these!

My dogs finally chewed pieces off of these bones but it took forever for them to do it and they didn’t chew very much off! These are great and I will buy more!
