First, we must be clear that dogs are man's best friend. They have accompanied us through many wonderful times, bringing us endless joy and warmth. However, when they no longer meet our expectations or, for some reason, we can no longer care for them, we cannot easily abandon them. Such behavior not only hurts the dog's feelings but also violates our responsibility and love for animals.
Secondly, the dog was abandoned on the balcony with only a piece of cardboard for warmth, which is undoubtedly a great torment for it. In the cold winter, dogs need sufficient warmth to withstand the cold. This piece of cardboard clearly cannot provide enough protection, leaving the dog to spend a long night in the cold environment. This attitude towards life is truly unacceptable.
Finally, we urge all dog owners to take full responsibility for their pets. No matter the reason, they should not abandon them easily. If you are unable to continue caring for your dog, you can choose to send it to an animal shelter or find another willing adopter. At the same time, we must strengthen animal protection awareness and education to raise people's understanding and respect for animal rights.
