What Is Theproper Dosage Of Flagyl For A 10 Lb Dog With Diarrhea?

I have a Yorkshire Terrier that ways approximately 10 lbs.  What would the proper dosage of Flagyl be for this size/weight of dog?  How many MG, how many times per day and for how many days?
Thank you.

Flagyl contains metronidazole and is used to treat bacterial and protozoan infections. Flagyl is an prescription drug. FDA has not approved this drug for animal use but vets are prescribing as extra label drug. Flagyl is indicated for infections caused by some bacteria, Giardia, Trichominas etc. Its dose in dogs is 10-60 mg per Kg body weight of dog 1-4 times a day depending upon severity of the problem. But this drug should be used under the supervision of a qualified vet.
