I got a 19 year old toughroughbred mare, she is sound and very sweet.. Although her previous owner had informed me that she has a sort of cough from being raced too young.. so she coughs alot, she has pills for it everyday though, and the more she's exercised the less she coughs, but now that is the least of my problems.. she seems to be loosing weight alot, and she isn't eating as much as she sould.. she's eating high fat and fiber, beat pulp grain and alot of hay.. but she's lost alot of weight.. She also was spoiled before I got her, they blanketed her all winter and kept her in a warm barn so her coat never really grew in, and now she's in a little colder of a barn but she's still blanketed with a winter blanket, I had the vet check her the other day and he floated her teeth, I thought maybe that could be a possibility to why she wasent eating all that much, he also said she has heeves.. I was thinking of giving her Senior feed, but I am really unsure of what to do.. I am looking to board her in a warmer barn but I don't know what to do about the weight issue and the heeves.. please help! Thank you.
