I found the article by googling "copd in horses" it is on the first page about midway down !! It is from LSU Equine center or something to that effect, and written by a DVM !! I would have to go back and look to get the names correct !! But I believe it is the only article on that page from LSU !!! On this site if you want to write someone privately, just click on their name and a drop down box will appear then click on "Send____ a private Message" !! If you still can`t find it yell back at me and we will figure something out !!
