I have a horse who gets bad seasonal allergies. He coughs and develops a heave line. last year I put him on Uckele Lung supplements. He done well on them but when pollen would increase so would his symptoms. I want to know is there any otc stuff or maybe natural remedies that might help with his asthma? With this I’m trying not to break the bank because a lot of the products cost a arm and leg and only half work but want to give my horse the most. I’ve heard about omega 3 and never tried it. Has anyone tried it?
