horse asthma attack

OJ having an asthma attack, lots of coughing and difficulty in breathing. He is always worse in summer as he suffers with allergies as well. Best treatment is steroids, but OJ can't have them so it has to be managed with up to 100 piriton tablets a day 4 scoops of ventipulmin and two sachets of Bute. If he ends up having an asthma attack like in the video then the vet has to be called out straight away.
