Desert foxes live in a warm climate, therefore it has to stay cool. It does this by having large ears as it reduces the body heat because the blood passes close to the surface of the skin through their ears. Remember a larger surface area allows more heat loss.

A fennec fox with small ears would overheat in its hot Saharan desert habitat. The fox's large ears help the fox to lose heat and stay cool.
The tunnel fox is commonly known as the Fennec fox. It is a small nocturnal fox found in the Sahara Desert known for its distinctive large ears and ability to dig burrows for shelter.
The fennec fox has very large ears. See image above.
Desert foxes have large ears to help regulate their body temperature in the extreme heat of their desert environment. The large surface area of their ears allows for better heat exchange and cooling through blood vessels close to the skin. Additionally, their ears also help enhance their hearing, allowing them to detect prey and predators in the open desert landscape.

Foxes didn't choose to have "large" ears and they don't. You may have seen the Fennec fox, they do have quite big ears. Why? They are desert foxes and must hear their prey. The desert is pretty calm and quiet, so the Fennec must hear for any prey possible. But no, not all foxes have large ears.
The fence fox, or fennec fox, has large ears primarily to help regulate its body temperature in the hot desert environment it inhabits. The extensive surface area of its ears allows for increased heat dissipation, helping the fox stay cool. Additionally, these large ears enhance its hearing, enabling it to detect prey and predators more effectively in the sparse, open landscapes of its habitat.
The Arab word for the desert fox is "ثعلب" (pronounced "Tha'lab"). In specific contexts, particularly when referring to the fennec fox, a type of desert fox known for its large ears, it is called "ثعلب الفنك" (pronounced "Tha'lab al-Fank"). The fennec fox is well adapted to life in arid environments.
