Great for teething puppies
Color: Dogwood (Brown), Size: Small (Pack of 1)
My pup absolutely loves this. Can keep him occupied for up to 45 min at a time. Pretty durable, too.

The best chew ever for a strong chewer
Color: Dogwood (Brown), Size: Large (Pack of 1)
We have a 77lb goldendoodle who loves these. We’re lucky because he doesn’t chew on anything other than his toys, but when he starts on this…he really goes at it. It’s healthy, (not synthetic), doesn’t break apart, (no pieces to worry about him swallowing), it just perfect for him. The noise may get on your nerves but it’s a small price to pay to keep him from chewing on your furniture, shoes, or anything else a mischievous dog can find.

Little pieces break off
Color: Dogwood (Brown), Size: Large (Pack of 1)
My dog is obsessed with this. It does last a long time even given her strong chewing capabilities. I wish it was a little bigger. The main reason I rated it so low is when my dog is chewing on this it breaks off a little plastic peice and sometimes it hits the back of her throat making her cough so you have to supervise with this.

Great for aggressive chewers
Color: Dogwood (Brown), Size: Large (Pack of 1)
My dog is an aggressive chewer so they are great for her. I would love to have one a bit thinner so it could fit in a holder so it is easier for her to hold while eating. This keeps her busy and is long lasting. I have purchased these multiple times.

I bought this interactive ball for my dog, and it has been an excellent purchase.
Color: Blue, Color: Blue
I bought this interactive ball for my dog, and it has been an excellent purchase. He loves playing with it because it moves and bounces on its own, keeping him entertained for a long time. It feels durable, is easy to charge, and is of very high quality. I would definitely recommend it to anyone looking for a fun, long-lasting toy for their pets.
