Hi Patrick and D_O-
I am using soft chew probiotics called ProFlora by PHS right now. I like them because I can easily feed them to my dogs without hiding in food or “masking” them in peanut butter or something. I have also used similar chews made by Vetri-Science. They think they are treats. I do have golden labs, however. They think everything is a treat. Lol! I give them in the evening a few hours after their dinner and they seem to work well. No stinky gas in the family room! They have 8 or 9 strains of probiotics and a prebiotic as well. Not sure if the chews are as effective, but they have been good for us so far. I buy them from Amazon or Healthy Pets websites. I find that Healthypets.com has some of the best prices on supplements. Hope this helps.
