Max had the runs all the time! The Vet couldn't do much, the only food what helped a little bit was science diet BUT it was not "perfect".
The next problem was, she couldn't eat rice potatoes NOTHING.
The only thing what really helped her to get it somehow under control was feeding her bones!
We now feed the bones and raw food diet and Max is fine! She can eat Potatoes now ( never uncooked thats not good at all ) and haven't been at the vet since!
So i would say bones are a good way to help against the run, i would recommend soup bones RAW in that case!
