Yes, two of my three take probiotics daily. One has recently been diagnosed with a bit of IBD & was moved to a low fat diet with daily probiotics added, just for good measure. So far, so good (going on three months in to this routine now)
The other one tends to be a bit of an indiscriminate eater when she's out roaming around in the woods on our property (she has a way looser definition of 'food' than I do! lol) and now that she's getting older (just turned 10) also has some increasing issues with 'empty tummy, acid refluxy urping) so she gets a daily morning dose of Pepcid, a snack at lunchtime & probiotics once a day. Also, so far - so good.
If digestive issues are temporary or ongoing, I feel that using probiotics falls into the 'might help, can't hurt' category. Also, if antibiotics have been given for any reason whatsoever, at least a couple weeks to a month of probiotics are pretty important (in my opinion & experience) to get everything back on track digestively.
