Recently a family friend who was facing finantial issues asked us to take care of her horse for her... Sam is now in our pasture but does not seem happy... At first we thought it was normal but now he is hardly eating hay(he has a healthy grain appetite) and now has a cough..... Any ideas or suggestions???? It makes me so upset because I don't have a lot of experience.... I want to buy him greener hay but the owner says she doesnt want to pay for it.... any suggestions???? Thanks!!
