Afternoon all. I have been offered a lovely horse that I know well for free as the owner is going off travelling. Horse is 18, will be 19 in May and is as honest and sweet as they come. She does, however, have Cushing's Disease (currently on 1.5 tablets of Prascend per day) and mild trouble with COPD. She has never had laminitis or been lame in the last 5 years. I really like the horse and I want her to have a good home, she is still rideable. Am I being stupid to consider taking this horse on? Is the Cushings likely to worsen dramatically as she gets older, despite the medication? Any opinions/experience most welcome!
