High quality toy loved by my dogs
Color: Brown, Pattern Name: Tree stump 2 Pack
These are amazing, my dogs favorite toys now. I have two strong chewers who haven’t been able to destroy these. I use yogurt, peanut butter and eggs, broth, really any dog friendly liquids to fill it. I recommend these to all my friends and family with dogs of all sizes.

Excellent Purchase!
Color: Brown, Pattern Name: Tree stump 2 Pack, Color: Brown, Pattern Name: Tree stump 2 Pack
My dogs and I really like these treat toys! I was surprised and questioning whether to keep them when I took them from the box. They are heavier and harder and larger than I envisioned. I didn't realize how hard a nylon/coffee wood combo actually is. However, I want to emphasize that the sales description IS accurate. It details the specifications, materials and size. Clearly states that they are designed specifically for aggressive chewers. I just haven't purchased anything quite like this before.
That said, I was happy it came in a 2 pack and it seems a good value for the price. The dogs have chewed on them, I can see the marks, but they haven't made a dent after about 6 treat sessions. These logs are at least as hard as antlers. They will last a long time. The silicone trays are easy to fill and freeze. I made low calorie popsicles with bone broth and some added mix-ins like pureed pumpkin, healthy freeze dried dog food topper sprinkle, etc. You could also add some peanut butter in the small open end of the log if you want. I just ran hot water over the bottom of the silicone tray to melt the freeze slightly and the frozen treats slid right out. They are shaped perfectly to fit the hole in the log. The seller provided small tools to unscrew/screw the cap in and out for filling with treats.
Even the smaller of my 2 dogs (30 lb Brittany) can get her mouth around the end of the log to carry it to her bed to lay and lick/chew it. I guess another advantage, beyond the durability, of the material is that my dogs don't want to play with it like a toy. They know it is time to relax and have a treat timeout. More like chilling with a chew bone.
Overall we really do love these!! Glad I tried them.

Durable, Engaging Toy That Actually Lasts
Color: Brown, Pattern Name: Tree stump 2 Pack
I’m really impressed with the ClariVora 2 Pack Dog Toys for aggressive chewers. My dog is a strong chewer and usually destroys toys quickly, but these have held up really well. The material is durable and tough without being too hard, which gives me peace of mind.
I especially love that they can be used as frozen treat toys. Filling them and freezing them keeps my dog busy for a long time and really helps with boredom and anxiety. They’re perfect for extending playtime and keeping dogs mentally engaged.
These toys are a great size for medium to large dogs, easy to clean, and have already become a favorite in our house. If you have a power chewer and want something interactive and long-lasting, I definitely recommend these.

Small but aggressive chewers love these
Color: Brown, Pattern Name: Tree stump 2 Pack
I have a Jack Russell and a chihuahua/jack mix (I know, I must have done something really bad in a former life and this is my punishment). They’re both aggressive chewers for their size. These hold up well and they love them. The silicon molds are really easy to use and clean. I spread a little peanut butter around the sides and then fill with wet food, pumpkin, Greek yogurt etc. Once frozen they pop out easy. Keep the kids busy for a solid 20mins. Just don’t over-tighten when you close them!

Amazing durable product for your fur babies!
Color: Brown, Pattern Name: Tree stump 2 Pack, Color: Brown, Pattern Name: Tree stump 2 Pack
We love this product! I have two aggressive chewers, one being a Staffordshire bull terrier, and the other great Dane mix puppy who is eight months old. They both love to chew and can be mischievous or anxiety ridden when they are bored and if they aren’t entertained with something. My Staffordshire bullterrier is a very aggressive chewer and we’ve had a hard time finding durable toys for her. This product is amazing. It keeps them entertained for at least an hour with the food that you can place inside. The molds are great and it’s really nice that I can make homemade dog treats to put in the toy. I use these toys every day, multiple times a day, and they’re holding up amazing. I love that the company includes the molds for the treats as well as a little key to open up the back of the toy to put the food in. This is a really good product. I have spent hundreds of dollars on toys and this one is worth the cost. I’ve tried bully box, Kong products, anything you can think of that says durability chewing, however this is really really good. I 100% recommend this product and I think it’s very fair pricing. Your fur babies will get a lot of playtime with this!!
