What is Metronidazole? Is it dog antibiotics?

250 mg BID, or half a pill twice a day is what dogs around 30 lbs are usually prescribed.

My mastiff was given this drug by his Vet for an ear infection, so it can be used for dogs.

Dear friend, more than a anti-biotic metronidazole is anti parasites. It works best against protozoa, flagillates. but this medecine is having side effects also and what i think is half knowladge is very bad. so never give it unless priscribed by doctor.

im hoping your friend too all of her antibiotic cuz that would mean that the bacteria could still be in your friends system! and also dont give a dog something thats not prescribed by a vet, thats just not a good idea

Personally, I would NOT give those to the dog. Flagyl the other name for those pills, are a very potent anti biotic and anti protozoan drug. Not all drugs for humans can be taken by a pet and if they can, a lower dose is needed. I have taken Flagyl before and will tell you that it will probably be too strong and has a nasty habit of making somebody almost projectile vomit. If your friend has a dog of about the same size and they were from her/his dog, you might chance it, but, haven taken it myself and knowing how strong it is, I would NOT give it to the dog.
