I've heard a couple coughs from a lamb after running, Its a non stop repeating cough like he has a fur ball stuck. It lasts for about 30 seconds then back to normal he's done it a few times in the last week. I worm my lambs every 28 days and it covers all stages of lungworm....

Is he just a bit unfit like myself or is there something more serious?
What are the signs of liver fluke?
