Background

CD20, also known as B-lymphocyte antigen CD20, is a 33–37 kDa non-glycosylated protein primarily expressed on the surface of B cells from the pre-B cell stage through maturity, but it is absent on plasma cells. It is encoded by the MS4A1 gene and belongs to the membrane-spanning 4A gene family. CD20 is a transmembrane protein with four hydrophobic transmembrane domains, one intracellular domain, and two extracellular loops. Although its exact biological function remains unclear, it is believed to play a role in B cell activation and proliferation by facilitating calcium influx. CD20 is an important therapeutic target for B cell malignancies such as chronic lymphocytic leukemia and non-Hodgkin lymphoma, as well as for some autoimmune diseases.

My dog loves them...but
Size: Small
The ball is firm, durable and bounces well, but the squeaker is a disappointment. My 16 lb chihuahua doxie mix is obsessed with squeaky toys. I bought the small size which is a good fit. These balls are a bit firm and hard to squeak but she is still able to squeak them endlessly. The squeaker only lasts a couple of weeks then it's just a ball that she ignores.

Great toy!
Size: Small Size
My Frenchie absolutely loves this toy!!! It keeps her occupied for a long time. Has held up well to her chewing, and she's able to pick it up and carry it.

Great toy for small dogs
Size: Small Size
Our dog, who weighs 13 lbs, loves this ball. I like the fact that there are no batteries involved. The furry exterior is great for her as she can pick the ball up with her small mouth. I'd recommend this toy be used under supervision as larger dogs and heavy chewers could tear it apart quickly.
