Donkeys and mules are both members of the equine family, but there are some key differences between them. Donkeys are typically smaller than mules and have longer ears. They also tend to be more stubborn and independent than mules, making them more difficult to train. Donkeys also have a reputation for being loud, braying animals. In contrast, mules are usually larger than donkeys, have shorter ears, and tend to be more docile and easier to train. Mules also tend to be quieter than donkeys.
Another difference between donkeys and mules is that donkeys are usually bred with other donkeys, while mules are a hybrid breed, created by breeding a donkey and a horse. This gives mules the strength and hardiness of a donkey, combined with the size and intelligence of a horse. Mules also tend to live longer than donkeys, with an average lifespan of 25-30 years, while donkeys typically only live around 20-25 years.
