Background

CD200 R1, also known as OX-2 receptor, is a 90 kDa, type I transmembrane protein that belongs to the immunoglobulin superfamily. CD200 R1 is important in the regulation of myeloid cell activity.CD200 and its receptor CD200R are both type-1 membrane glycoproteins, which are members of the immunoglobulin superfamily (IgSF). Besides the inhibitory effect on macrophages, CD200/CD200R also play an important role in regulating the regulatory T cells, allergic reaction, autoimmune diseases, allograft, neurological diseases and other autoimmune-related diseases. The interaction between CD200, which is mainly present in neurons but also in astrocytes, and CD200R1, which is mainly present in microglia, is one of the mechanisms involved in keeping the microglial proinflammatory phenotype under control in physiological conditions. Limits inflammation by inhibiting the expression of pro-inflammatory molecules including TNF-alpha, interferons, and inducible nitric oxide synthase (iNOS) in response to selected stimuli.

Thinks a fun little sniffy toy
Color: blue, Color: blue
My puppy seemed curious and didn’t mind playing with this sniffy toy. It’s large and well made and has plenty of title spots to hide stuff. I put kibble in it and my little puppy sniffed and googled a way. I guess this is great for keeping dogs busy and entertained. It’s a pretty cool little way to give dogs treats or snacks.

Great for dog who loves chewing small “tags” on stuffies
Size: Rabbit & Pig
My dog loves chewing the small tags or ears etc on plushies. He will pick one ear to chew on the little stuffed dogs from Petco, chew it until it’s starting to get shredded and I have to cut it off, then switch to the other. I picked these toys specifically because they have SIX little tag-like parts that stick out, not just the two ears. He loves them! He is a 10 lb maltipoo and can easily grab and run with these. Loves the crinkle paper inside, loves the squeaker in the head, and LOVES the little parts that stick out for him to chew. We just got them today so time will tell if they are durable, but they seem well constructed and he’s happy, so I’m happy. Update: it’s been a week. I gave him one of the toys and he of course chose one ear to focus all his chewing on. That ear has been chewed and chewed and it is just getting to the point it’ll need to be trimmed off soon due to raggedness. Then he’ll still have five little nubs left on this toy to chew. So it should take him at least 6 weeks to chew all of them. By comparison, when we get cheap stuffies on Amazon, usually both ears are totally finished within a week or ten days. This is definitely more durable and worth the money!
