I have a cow that I think has foot rot, I got her up and gave her a dose of la200, well,after a couple of days she did'nt get any better. She had a calf 3 days ago and I can't get her to come to the barn, I'm sure she will come in a day or two she normally does all her thinkin with her stomach. My question is how long can you go with foot rot before it is too long?
