Background

IL-31 which produced by activated Th2-type T cells. IL-31 signals through a receptor composed of IL-31 receptor A and oncostatin M receptor. IL-31 activates STAT3 and possibly STAT1 and STAT5 through the IL-31 heterodimeric receptor composed of IL31RA and OSMR. IL-31 has also been identified as a major player in a number of chronic inflammatory diseases, including atopic dermatitis. Patients with atopic dermatitis, chronic spontaneous urticaria, allergic contact dermatitis, prurigo nodularis, primary cutaneous lymphoma and mastocytosis exhibit increased serum levels of IL-31 protein and elevated IL-31 mRNA in the skin.

The dog loves 'em
Color: Blue
The dog loves the balls, and they're the right size for my German Shepherd. Lost a couple of starts because they're not very durable, the "teeth" are easily broken off, so I am frequently finding "lost teeth" across the house; the squeakers also cannot hold up to my dog's aggressive chewing. I would still buy them again, as like I said, my dog love 'em!

Dogs love them!
Color: 3 Colors
Dogs love them! Larger than your average tennis balls, satisfying for my dogs to chew on, the squeak isn't too annoying, colorful enough I can find them in the bushes.

Great product at a great price
Color: 3 Colors
I bought these for my heeler/border collie mix. She destroys every toy almost immediately. They are her favorite toys and plays with them daily. They are still in great shape after 4 months. They have a squeaker, but it is not one of the obnoxious loud ones.

Fun Dog Fetch Balls
Color: 3 Colors
Ordered these for my dog for Christmas and he loves them. He has a blast running up and down the hallway with them. Easy to play with, cute and fun. Not very noisy, I actually didn't know they squeaked until I stepped on one. Very quality and sturdy. Good value for the money. Package arrived timely and as described. Would definitely order again.

Tough ball. Perfect for large chewing breeds.
Color: 3 Colors
My German Shepherd Dog is a year and half old, and she loves these. They truly are pretty indestructible. It took her a little bit to figure out how to squeak it bc they are tough, but now it’s easy for her. They bounce well too. They are larger than a normal tennis ball but a good size for a large dog. Luna is 85 lbs. I would purchase they again, but I probably won’t need to for awhile.
