I was wondering if anyone has any advice. I have just bought a 9 year old danish warmblood. Since buying him he seems to have a few issues that werent evident when I bought him. When he's being ridden his breathing sounds deep and quite heavy and chesty and he always has a good cough as soon as we start trotting which then doesnt re occur during the schooling. He has started to get quite worked up pulling and jumping around doing a few mini bucks and rears and when he does this he usually gets about 2 or 3 nose bleeds after he's been ridden. Could the breathing, stress and nose bleeds be related? I have spoken to the vet who thinks its just normal to have a nose bleed when he gets worked up but should I be worried? It is only out of 1 nostril and starts mucusy but then turns very red. He passed a full five stage vetting when I bought him 2 weeks ago.
