Background

CD28 (Cluster of Differentiation 28) is one of the proteins expressed on T cells that provide co-stimulatory signals required for T cell activation and survival. T cell stimulation through CD28 in addition to the T-cell receptor (TCR) can provide a potent signal for the production of various interleukins (IL-6 in particular). CD28 is the receptor for CD80 (B7.1) and CD86 (B7.2) proteins. When activated by Toll-like receptor ligands, the CD80 expression is upregulated in antigen-presenting cells (APCs). The CD86 expression on antigen-presenting cells is constitutive (expression is independent of environmental factors). It is generally reported, that CD28 is expressed on 50% of CD8+ T cells and more than 80% CD4+ T cells in human, but during the course of activation some T cells lose this molecule. In general, CD28 is a primary costimulatory molecule for T cell activation.

Small but aggressive chewers love these
Color: Brown, Pattern Name: Tree stump 2 Pack
I have a Jack Russell and a chihuahua/jack mix (I know, I must have done something really bad in a former life and this is my punishment). They’re both aggressive chewers for their size. These hold up well and they love them. The silicon molds are really easy to use and clean. I spread a little peanut butter around the sides and then fill with wet food, pumpkin, Greek yogurt etc. Once frozen they pop out easy. Keep the kids busy for a solid 20mins. Just don’t over-tighten when you close them!

Amazing durable product for your fur babies!
Color: Brown, Pattern Name: Tree stump 2 Pack, Color: Brown, Pattern Name: Tree stump 2 Pack
We love this product! I have two aggressive chewers, one being a Staffordshire bull terrier, and the other great Dane mix puppy who is eight months old. They both love to chew and can be mischievous or anxiety ridden when they are bored and if they aren’t entertained with something. My Staffordshire bullterrier is a very aggressive chewer and we’ve had a hard time finding durable toys for her. This product is amazing. It keeps them entertained for at least an hour with the food that you can place inside. The molds are great and it’s really nice that I can make homemade dog treats to put in the toy. I use these toys every day, multiple times a day, and they’re holding up amazing. I love that the company includes the molds for the treats as well as a little key to open up the back of the toy to put the food in. This is a really good product. I have spent hundreds of dollars on toys and this one is worth the cost. I’ve tried bully box, Kong products, anything you can think of that says durability chewing, however this is really really good. I 100% recommend this product and I think it’s very fair pricing. Your fur babies will get a lot of playtime with this!!

Good puppy toy
Color: Brown, Pattern Name: Tree stump 1 Pack
Keeps the pup busy. He is not able to bite through it, it is very durable. Only gave 4 stars because it only takes him about 15 minutes to go through it and hes onto the next thing. Love that he is not able to destroy it though like other toys.
