Thank you ksalvagno, you have been extremely helpful! I really appreciate it, and I really appreciate everyone else help also!I would just clean him up and go from there. It does take time for their system to adjust and the poop to look normal. It doesn't look like scours. I have never used the powder probiotics so don't know how much you would put in a bottle. You won't have to permanently do this, just enough days till their system is used to everything new.
