okay so my dad has asked me to post a question about one of our horses i was going to post it on backyardherds but thought id ask you all first. so our horse buddy has a problem that we just noticed, hes always soaking wet and filthy, even when its not raining we were thinking it was sweat but the other day my dad noticed it was kind of yellowish looking and oozing from his skin, not clear like sweat is and also his fur isnt smooth and soft like my other horses its kinda rough and missing in small patches, could be from rubbing but it looks mangy to me any ideas on what could be wrong? we dont have alot of money right now so we wont call the vet unless we really have to. but any suggestions of what it could be would really help.
