Great for Chewers!
Flavor Name: Chicken, Size: 7 inch (Pack of 1)
Purchased for my German Shepherd Pup a few months back and itβs still going strong! It is by far his favorite chew toy. It clearly lasts a long time. Itβs a nice size with some weight to it. Good for them chewers!

Not for aggressive chewers
Flavor Name: Bacon, Size: 5.25 inch (Pack of 1)
This bone is noticeably softer than most chew toys I've bought. That may be a positive for some dogs, but my dog was able to break off fairly large pieces, which made me nervous. It might work well for light chewers, but I wouldn't recommend it for aggressive chewers.

Bacon? IDK but good stuff either way
Color: C) 4" 2-Pack (Bacon)
What is there to say? they're giant 4" rubber balls from the Chew King brand which is very durable brand. The best part is they don't roll under couches, side boards, etc cause they're just big enough.

Tough Dog Balls. Bright Orange/holes for treats
Color: B) 3" 2-Pack (Bacon)
I used to buy Starmark. But their balls got smaller and tore more easily. The color was green. I couldnβt find it when it was dropped in the grass!! Soooooo, I took a chance on this cuz it had holes in it and was bright orange. It is not scented at all or its bacon scent faded. The ball is for strong chewers. Iβm a petsitter and I needed tough balls for my clients dog. Shipped quickly. Good price. Exactly as described
