Mare reproductive challenges can range from endometritis to ovarian irregularities such as hemorrhagic anovulatory follicles, ovarian hematomas, and persistent corpora lutea, all of which can disrupt normal cycles and fertility. Older mares often face anatomical complications that increase contamination and impair conception. Hormonal tumors such as granulosa-theca cell tumors might spur erratic behaviors and cycle abnormalities, while pituitary pars intermedia dysfunction (PPID, formerly Cushing’s disease) can further dampen reproductive performance by causing abnormal cycles, anovulation, and recurring endometritis. Vigilant diagnostics—including ultrasound, hormone panels, and uterine evaluation—are essential in identifying and managing these issues efficiently. 

During this Ask TheHorse Live Q&A two experts answer your questions about common mare reproductive problems.

Hind-limb lameness in horses can be challenging for owners to spot and veterinarians to diagnose. It can affect horses of all ages and disciplines. Subtle signs, such as a shortened stride, reluctance to go forward, or toe-dragging might go unnoticed until the horse’s performance declines or a more obvious issue appears. Catching hind-limb lameness early can improve your horse’s well-being and long-term soundness. Two experts answer listener questions about recognizing, diagnosing, and managing hind-limb lameness in horses in this archived Ask TheHorse Live podcast.

Researchers suggest 54% of horses in the U.S. are overweight or obese, putting them at a higher risk of developing other health problems, such as metabolic issues and joint pain. However, horses might become underweight due to gastrointestinal problems, such as gastric ulcers, or chronic health challenges. Regardless of whether a horse is under- or overweight, the underlying cause is usually an imbalance between the supply of energy the horse receives and the energy he expends. The first step in managing your horse’s weight is to determine his body condition score and work with an equine nutritionist to develop a nutrition plan to meet his needs. Tune in to learn how to manage your horse’s weight whether he is over- or underweight.

Equine osteoarthritis (OA), or the degeneration of cartilage and bone in a horse’s joint, is a painful condition and the most common reason for lameness in horses. While there is no cure for OA, horse owners and veterinarians can work together to delay onset and slow its progression. Without treatment, OA can result in poor quality of life, early retirement, and even euthanasia if the associated pain is no longer manageable.
