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 couldn’t 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. I’m a petsitter and I needed tough balls for my clients dog. Shipped quickly. Good price. Exactly as described

Flavored Dog Rubber Balls
Color: H) 2.5" 3-Pack (Beef), Color: H) 2.5" 3-Pack (Beef)
My dog absolutely loves these balls, I have a few more I had already bought, but she has an addiction to them so I had to buy more. I am able to squeeze these really easily so when she does pick them up after I’ve thrown them they’re very easy for her to pick up. They have a good thickness to them so it’s not too flimsy. It’s pretty tough and they bounce pretty high which I like and so does she know she is an aggressive chewer, but I haven’t had an issue yet with her chewing right through these, which is why I like them and we both love the fact that it smells like beef I could practically smell them through the bag, but I have a really high pitched sense of smell, and I knew she was going to love them. Not to mention you can’t beat the price.
