The vet didn't mention a test, but I'll need to ask about the possibility of doing it.
I'm giving them good hay that smells fine to me, but my dad is keeping a huge pile of old, bad quality, dusty hay that he planned to feed to the sheep, right next to the goat pen. I can't smell it from far away, but maybe that is doing some harm? It's going to be burned soon, but moving it will be difficult, and and he is waiting for a day when the wind is strong and isn't going towards the fields.
They are all the same age and breed, bought from the same place and raised together. I believe all the tests have been done as its a reputable farm, and they had him on a regular worming schedule.
He has a good coat and has been wormed regularly, but are lungworms still a strong possibility?
The coughing always happens after a long run or when he's been playing with the other two. It's like a dry coughing fit, sometimes he coughs once or twice, but other times he coughs quite a few times.
The vet has been here twice, but maybe I'll call soon?
