Foreigners' passion and enthusiasm for raising dogs can be illustrated from the following aspects:

First of all, dogs have always been very popular and encouraged pets in foreign cultures. In many western cultures, it is generally believed that dogs are man's best friends. Therefore, keeping a dog is widely regarded as a pleasant, caring and intimate activity.

Secondly, for those who can't have children because of work or family reasons, dogs are especially a kind of life that can fill the emptiness. They are willing to spend a lot of time and money to take care of them, make them a member of the family and buy them all kinds of toys and snacks.

Besides, dogs have become an increasingly popular social activity. Many dog owners will take their pets to public places such as walks, parks, gyms and even coffee shops to communicate with other pets and owners. Through communication with other dog owners, people can support each other, encourage each other and share life experiences.

Finally, dogs can also be therapeutic pets. They can spend time with people with psychological and emotional problems to help them relax. In addition, according to some research results, getting along with dogs can reduce people's stress and anxiety.

In short, foreigners' enthusiasm for keeping dogs can be attributed to their love for dogs and their recognition of dogs as pets and life. Dogs are one of the best friends of human beings, and this friendship can bring countless joys and happiness to people.
