Full recovery in 48 hours! Thankful for this.
Recently, out of nowhere, my Lab woke up in the middle of the night and barely made it outdoors before he exploded with massive diarrhea. This continued all night, every couple of hours, and into the next day even once we started him on canned pumpkin and bland diet. I felt so bad for my boy. In the past my vet would always prescribe Tylan powder if he ever experienced sudden onset diarrhea. For some reason, this time they said the Metronidazole would be better (maybe because he's now almost 2, or perhaps this works faster). Anyway, we immediately started him on the recommended 1.5 pills, every 12 hours. The pills aren't huge so I was able to tuck them into a little cube of rolled dog food. Within 48 hours, so 4 doses total, he was 100% better even once I re-introduced his kibble. Firm poop, sleeping through the night again. We still have a few pills left over and I'm happy to have them on-hand in case he ever has a bout of belly issues again. This stuff works!
Helped my cat
My cat has IBD and this has very much helped him with his bowels and vomiting.
Metronidazole
Can these be purchased in 100mg? My dog needs 25mg a day.
Works like a charm
My Collies have sensitive stomachs, which in turn leads to upset intestinal systems on occasion. Metronidazole works like a charm. It usually takes about 12 to 24 hours to kick in. I don't feed my dogs for a day after the onset of the intestinal disorder, but immediately give them this. Then it's chicken, or pumpkin, or turkey and rice for 3-4 days. After 5 days on the medication, I can stop giving it. Don't think the cure is a single dose. I can't live without this. :)
