It seems to me, that what the above products have in common, is that they are all appear to be made from either full thickness or partial thickness untanned cattle skin This company also makes several brands of chews labeled as beefhide. Ĭompany E, unlike A-D, doesn’t seem to claim their collagen chew is a “rawhide alternative” or say it is not hide. A tannery resides at the same address as this chew maker, who also appears to market beef hide chews under a different brand name, which look to me to be the same in appearance to their “hide free” chews. I don’t know how they are defining “hide” but it seems they may be defining hide as the top split of the corium and then claiming that the bottom split is hide free. Under magnification their product appears to me to be a tangle of fibers which is how corium and traditionally labeled rawhide also appears to me.Ĭompany D said the raw material they use in their “rawhide alternative” chews is corium which is also used for human food production, and that no hide is used in their products. The email stated that all information was proprietary. When asked if their product was corium, customer service said the answer to my question would be emailed to me. Note that their definition of what is rawhide looks to be the opposite definition than that of company AĬompany C’s collagen chew appears to me to be identical to company B in size, shape, color, and country of origin making me wonder if they are the same chew being imported by two different companies. Not sure what is meant by this, since technically, water is a chemicalĬompany B seems to say their collagen chew isn’t rawhide because rawhide consists of all layers of the skin and their product is only the lower split of corium. Finally, it looks like they are saying their product doesn’t use chemicals in processing. Additionally, they seem to say that since their product is full thickness skin, and rawhide is the lower split.of the corium, their product is not rawhide. I find the reasons given from the manufacturers of chews made of full thickness cattle skin or corium, as to why their product is not rawhide, interesting.Ĭompany A appears to report that their untanned cattle skin product is not rawhide because it is sourced from the head of the cow and they seem to define hide as skin as coming from the trunk of the cow. chews.ĪAFCO doesn’t define the word “rawhide”, Merriam Webster defines it, in this context, as “untanned cattle skin” The tanner splits the corium into upper and lower layers, The upper is used to make leather, the lower is used as a source of collagen for sausage casings, drug capsules, supplements, gelatin etc, to make rawhide chews, and now apparently some “rawhide alternative”. Hides are sourced at slaughter and sent to a tannery where they are dehaired and fleshed ( the fat layer under the skin is removed). The chew traditionally called rawhide is a by -product of the leather industry. Some new “rawhide alternatives” being marketed appear to me to simply be rawhide renamed
