HELP! Sundae is on Baytril and is having soft poops as a result. I want to start her on a probiotic tomorrow to help ease her digestive tract. The pet stores in our area don't seem to carry any probiotics aimed at guinea pigs- they do have some aimed at dogs, and of course it's easy to find them for humans, but I have no clue if this is safe, what the dosing should be, or what active ingredients I am looking for. Can anyone tell me what I need to look for in a safe probiotic for guinea pigs? Thanks in advance!
