1. Dental Issues
As they age, horses tend to develop issues with their dental health. Years of uneven grinding can result in uneven wearing of the teeth, loose molars, and incredibly sharp points. Your horse may also experience abrasions in the tongue and cheeks, which could result in difficulty eating and eventually, weight loss.
2. Arthritis
Although arthritis isn’t just an issue among older horses, the condition tends to worsen with age. You’ll find that most horses that are older than 20 will have some arthritis. The reason for this is because the proteoglycans in the cartilage such as hyaluronic acid and chondroitin sulfate decrease as they age, causing wear and tear on cartilage and joints Additionally, horses lose muscle mass as they age, making their tendons and ligaments weaker. This will then negatively impact the joints because the tissues help in stabilizing the joints to prevent abnormal movements. Light exercises are crucial for preventing and alleviating arthritis symptoms. If possible, let your horse graze all day in the pasture. And if your horse is overweight, you should start managing its weight to prevent excess weight from straining its joints.3. Equine Cushing’s Disease
Another common health problem among older horses is equine Cushing’s disease. This is a result of a portion of the pituitary gland being overactive, and is normally seen in horses that are around 20 years old. A horse that has Cushing’s disease may drink excessively and urinate excessively and may even have a pot belly. And if the horse has a long, wavy coat, it may not shed during summer. Horses with Cushing’s disease may also have a weakened immune system, and they are predisposed to other conditions such as laminitis. They may have recurrent infections that have no probable cause. Your vet will need to do several blood tests to diagnose the condition. Although there is no cure for it, there are medications that can help manage it.4. Weight Issues
It’s extremely common for older horses to have trouble maintaining a healthy weight. As mentioned earlier, dental issues can prevent a horse from eating properly and thus maintaining a healthy weight. Even if there isn’t trouble with the teeth, other unrecognized pain such as abscess or pain in the jaw can be the cause.
