City sounds: distressful fox yelps in urban setting

In the bustling city of Berlin, a unique urban wildlife presence has become a common sight - the red fox. With an estimated population of around 4,500, these creatures have adapted well to city life, feeding on a diet primarily consisting of mice, rats, earthworms, human waste, and fallen fruit.

However, occasional encounters between foxes and dogs can lead to some concern among pet owners. Foxes, by nature, tend to avoid dogs due to their strength. Yet, reports suggest that around ten such attacks are reported annually, particularly against small dog breeds like Chihuahuas. These incidents are often associated with mothers defending their cubs, a behaviour that is a natural response to potential threats.

As the young foxes grow, they enter a critical phase known as the weaning process. This phase, which lasts several more weeks, marks the beginning of the parents' withdrawal and the stopping of food provision. During this time, the young foxes can be heard making loud noises at night, a natural part of their development process. These noises, caused by their calls for food, should not cause concern to residents, as they are harmless.

The weaning phase is a challenging time for the young foxes, as they have to find their own territories in a city like Berlin, where most territories are already occupied. By September, the young foxes are still tolerated in their parents' territory but are no longer fed. In October, the young foxes become sexually mature and have to find their own territories, as "Mom's hotel" is no longer available.

It's worth noting that a dog is considered a pet, and its owner is responsible for ensuring the pet's safety. To protect dogs from fox attacks, it's recommended to keep dogs on a leash, especially during nighttime, when most incidents occur.

While attacks by dogs on foxes are not typically reported by owners, the loud noises made by the young foxes can be heard in various locations such as inner courtyards, underpasses, and on house walls. The young foxes use the acoustic amplification deliberately to reach their parents, a strategy that helps them during the weaning phase.

In conclusion, while encounters between foxes and dogs can sometimes lead to concerns, understanding the natural behaviours and development phases of these urban creatures can help alleviate worries. By following simple precautions like keeping dogs on a leash, especially during nighttime, pet owners can ensure their dogs' safety while coexisting harmoniously with Berlin's urban fox population.
