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. 🦞🐾

Dog approved.
Size: X-Large, Color: Cheese
I’m a 70 lbs Goldendoodle (supposed to be 65, don’t ask) and I love cheese. Real cheese. Sharp cheddar with sourdough bread is my dream, but apparently I’m “on a health journey,” so my people bought me this instead. Does this bone actually taste like cheese? No. I am not fooled. Do I still enjoy chewing it loudly while my humans are trying to watch TV? Absolutely yes. This bone satisfies my need to chew and my emotional desire for cheese-adjacent activities. It keeps me busy, saves the furniture, and lets me crunch dramatically during important dialogue scenes. The yellow color is nice — very cheese-coded — although some cheeses are white, so just something to consider for future versions. Also, good news: it doesn’t smell like cheese at all, which my humans seem very grateful for. Apparently they don’t want the carpet to smell like a deli. Weird. Final verdict: Not cheese. Still enjoyable. Would chew again. ~Barley
