A woman who rescued a “dangerous” horse from being euthanized discovered that he was actually suffering from a painful condition. The horse, named Moonlight, was labeled as aggressive and untrainable by his previous owners. But his new owner found out that he had ulcers in his stomach and mouth, which made him irritable and sensitive. After treating his ulcers, Moonlight became a calm and loving horse.

A farm in Texas revealed a rare cross between a miniature horse and a donkey, which they named “Minnie”. The adorable animal is a hinny, which is the offspring of a male horse and a female donkey. Mules and hinnies are usually sterile, but they are very smart and friendly animals.

A new study has found that genetic improvement is underlying the increasing speed of Britain’s thoroughbreds. This contrasts with earlier studies that suggested racehorses were showing no genetic improvement in response to selection by breeders. The researchers analyzed the performance of more than 70,000 racehorses over 120 years and found that they have become faster by about 16 meters per minute.
