I have tried something similar, it was in a tablet form though. It said within 7 days he will not want to eat it anymore yet he still persisted so I doubled the dosage for another two weeks! After it didn't solve the problem I took him off of it.
I can't recall what it was called but it worked on my aunt's dogs so she gave me some.
I will give this a try though, i'm willing to give anything a try.
We also buy our dog expensive dog food because we were told that this would fix the problem. I actually think it made it worse...
