Wow, tons of great info, and as I remember, when I was in this forum a while back, you gave me good info then too. Thank you so much...exactly what I was looking for. I will be reading up over the next few days and purchasing books. Did you happen to know of any food thats ok to be feeding in the meantime while I'm getting ready to start the switch? Right now they are eating Pedigree dry. I have just started giving the Boxer Syn-Flex, waiting on the Ester-C and MSM powder to arrive. I got a sample of that Doggone pain, and it was only 2 pills and I had already started the Syn-Flex so, it will be hard to tell if it worked, have you heard anything about the 2...the Syn_Flex and the Doggone Pain? Thank you again so much for all the info and links, my babies thank you too ;)
