Background

CD276, also known as B7-H3, is a type I transmembrane glycoprotein belonging to the B7 family of immune co-stimulatory molecules that is broadly overexpressed on the cell surface of many solid tumors while showing only limited distribution in normal tissues; it modulates both adaptive and innate immunity by interacting with putative receptors on T cells and NK cells to either inhibit or enhance anti-tumor responses, serves as a marker for cancer progression and poor prognosis, and is actively pursued as a therapeutic target through monoclonal antibodies, antibody–drug conjugates, CAR-T cells, and bispecific T-cell engagers.

Best and most durable toy for our German shepherd
Size: Medium, Style: Ultra Tug, Size: Medium, Style: Ultra Tug
We have a German shepherd. This is our 2nd purchase. The first one was her first and favorite toy. We still have the first one. But the strap broke (after a year) bc we didn't realize she hid it under blanket, and she chewed it in half. But after a year of hard play, the strap was worn out. She still plays with her ball, and often carries it with her on her walks. It throws well and I love not having to pick up a slobbery ball. The ball is soft, durable, safe, and easy to play with.

Cord is not durable. Not for unsupervised play.
Size: Medium, Style: Ultra Duo Tug
My dog loves this toy and chewed through the tether in about 15 minutes, making it pretty useless as a tug toy. So the cord is not durable as stated. This is not for dogs who love to chew. Also, it is a bit smaller, much more squishy and chewable than a tennis ball, and I was worried she would chew it apart and that it might get stuck in her throat without the tether, so I took it away, much to her disappointment.

Puppy's favourite, but not built to last.
My puppy absolutely adores this tug-of-war ball! However, I have to mention the durability—it started fraying after just a few days of use. While it’s still usable, the material doesn’t hold up well to enthusiastic chewing and tugging. If your pup is a strong chewer, this might not last long. That said, for the price and the joy it brings my puppy, I’d still consider buying it again—just with the expectation that it’s more of a short-term toy. Great for light play, but not built for heavy-duty tug sessions.
