Have him checked for emphysema? They can get this
from dusty hay. Over the past 35 years, we've had two horses with this
condition. They could take air in, but had to push hard to get it
out..."double expiration." It is not a cheerful prognosis if he does
have it.
I have a 10 yr
arab/quarter who competed successfully in endurance several years ago.
The previous owner let him sit for over a year before I bought him. I
have had him 4 months. He is now in condition however his resting resp.
is usually 16, at work it rises to 160 + . His nostrils are usually
quite flared, trying to take in air. His respiration recovery rate is
3-4 times as long as my other horses. Vet has checked him, heart, temp
are great. I have tried galloping him up short hills to get him to take
longer, deeper breaths. I live in central ca and he is not kept in an
inside stall so small airway disease is unlikely. any ideas?
