Background

Guanylyl Cyclase C (GUCY2C), also known as heat-stable enterotoxin receptor, is a type I transmembrane protein of the guanylate cyclase (GC) family expressed by intestinal epithelial cells from the duodenum to rectum. Mature human GUCY2C consists of an extracellular domain (ECD) with a ligand binding domain, a transmembrane segment and a cytoplasmic region possessing a kinase and GC catalytic domain. Endogenous ligands of GUCY2C include guanylin and uroguanylin. GUCY2C in epithelial cells plays an important role in cell dynamics and homeostatic balance of proliferation, metabolism, and differentiation that organizes the guanylyl cyclase C hormone axis. GUCY2C is also expressed in the brain and is implicated in attention deficiency and hyperactive behavior. The activation of cyclic guanosine monophosphate (cGMP), a second intracellular messenger, can stimulate the production of cyclic guanosine monophosphate (CGMP), which plays a role in regulating homeostasis, maintaining intestinal barrier function, and exerting anti-inflammatory activity.

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.
