We have a hamp/york cross (approx 50-60lbs) that is coughing. It has done this several times in the past couple of days, but I thought it was just hacking on some of the food or something. This am it sounded more conjested though. How can I tell if it is worms or something that needs to be treated more aggressively? We bought the pig last week from a reputable "show pig" farm, so I thought I would call later tonight to find out what they have already done with the pig. Any advice you all could provide would be greatly appreciated though.
