I realize that this is an old post, but thought I would see if anyone is still watching. I’m currently going through the same dilemma regarding dicalcium phosphate and tricalcium phosphate. I had decided that I was going to avoid all forms of calcium and sodium phosphate for a while for my dog that is having health issues. But it sure is limiting to do that, so I’m now weakening on that decision. Any more thoughts out there on whether these are potentially harmful, and whether the sodium versions are worse than the calcium versions? Many sources say that Sodium tripolyphosphate (STPP) is bad news in dog food and some mention Tetrasodium Pyrophosphate (TSPP). Just the names sound worse, but I wonder if they actually are any worse than DCP and TCP.
I see that one of the replies mentions Steve’s raw frozen. Ironically, contemplating trying this food is what got me thinking about DCP again. It seems that they previously included it in their foods but possibly have stopped. The local stores who carry it show dicalcium phosphate as the last ingredient. But on the Steve’s website it is not a listed ingredient. I sent Steve’s an email asking about it but have not received a reply.
I must say that the post from Corinne J about Steve’s did get my attention. I had thought that they were pretty reputable, but I am now wondering . . .
