What is a good probiotic?

[LeeLuMonster]

So I had to take Leelu in for an overgrowth of 'bad' bacteria (can't remember the name of them) that was most likely caused by gastroenteritis. The vet said to use fortiflora to help when her stools were softer and I was wondering if there was anything better available in Canada? I am in the process of switching from Chicken Soup to Before Grain dry as she barely eats her canned (go grain free). She only started having probs when she was on the Chicken Soup so I'm assuming there's something in there that does not agree with her, but I digress..
So something like fortiflora but better?
Thanks for any suggestions!!

I use Holistic Select - Digestive Aid - Holistic Transition but not nearly what they say too. I think it says 1 tablespoon/day...I sprinkle a tiny bit on their food at each meal as it were salt/pepper.

There are stores in your province that sell it - you can use the store locator to see if there are any of those stores close to you.
