Yes, that should be just fine. If it doesn’t work, you might want to try a probiotic that is made specifically for dogs rather than the human version. That’s because the bacteria in them are different, as they are in the human versus canine intestinal tract. But the human acidophilus will not do your dog any harm. For some dogs, it works well. For others, the canine products work better.

You didn’t say what’s going on with your dog or why she needs the probiotic. But good luck to both of you. I hope she feels better soon if she’s sick.
