Background

Fc is a crystallizable fragment composed of the carboxyl terminal of two kinds of immunoglobulin heavy chain, which is connected to each other by disulfide bond. The Fc fragment contains the carboxyl terminal part of the heavy chain fixation region, which is responsible for the effect function of immunoglobulin (complement fixation, binding to the cell membrane through Fc receptors, and placental transport). It is reported that IgG1 Fc, as a potential anti-inflammatory drug, plays a new role in the treatment of human autoimmune diseases.

The Best!
Color: Croissant
Out of all the stuffable, freezable dog treat toys I’ve tried over many years with several dogs, this one is #1! So easy to clean and freezing the little goodie cup that you insert in to the toy is so much easier than trying to stuff a small hole! The extra little grooves on the outside I fill with no sugar no salt peanut butter and my pup loves it! This is a heavier toy, so not sure how a small dog would do picking it up or carrying it around, but our 45 lb guy has no problem! Seems like it is very durable and just might last forever!

Bump on tongue
Color: Croissant, Color: Croissant
It’s a good idea but should be made with hard rubber and the back should not be able to come off. It gives off shards of plastic and gave my dog bumps on his tongue. I do love the idea and it keep my dog busy in the morning while I had my first cup of coffee and before everyone woke up.

My dog loves these
Color: Dogwood Flip N Chew, Size: Medium (Pack of 1)
I think this is the 2nd or third I have ordered of this toy. My shepherd mix absolutely loves them. He is a power chewer and these last a few weeks. The shape is great too - he quickly learned how to hold on to it with his paws for maximum chewing efficiency.
