Shark dog approved
Size: Large, Color: Broccoli, Size: Large, Color: Broccoli
My new baby shark.... I mean puppy really enjoys chewing. I can't just give her a ton of pig ears or bully sticks all day, which she would definitely love, so I'm constantly looking for well made chew toys. I'd put this right up with Kong. Very durable and nice. I also love the different textures, she seems to also love it. She can gnaw at the top and chew on the stem. She wanted it as soon as I opened it - it does smell like bacon but I haven't taken a chomp at it to be able to write a complete review!
My dog is about 23 lbs but I can see a 80 lb dog chew this, it's not small.

So cute
Size: Large, Color: Pumpkin
My French Bulldogs have really strong jaws and are aggressive chewers. These really are sturdy and last a good amount of time. They are a bit heavy and awkward for my dogs to hold onto but they do like them.

Cute toy and super tough!
Size: Small, Color: Lobster
My small dog is a serious chewer, and this lobster toy has been holding up great. Usually, he destroys toys within a day, but this one’s still going strong after a couple of weeks. The shape is perfect — easy for him to grab and chew, and the little claws keep him entertained.
The filet mignon flavor must be good because he goes right for it every time. It’s sturdy without being too hard on his teeth, and it doesn’t leave any mess or pieces behind.
If you’ve got a small but mighty chewer, this one’s definitely worth it. Cute design, lasts forever, and keeps my pup busy — total win. 🦞🐾
