There are many ways to make a dog die unknowingly, such as locking the dog alone on the balcony. Nowadays, everyone likes small high-rise buildings that are transparent from north to south and facing the sun. There is enough sunshine and the floor is high. In summer, the balcony can be regarded as a huge steamer. Needless to say, we will definitely not open the windows and close the balcony door, lest a bit of cold air escapes from the house. Then put the dog on a closed balcony and it will die in just a few hours.
Many dogs are still banned from some public places, such as shopping malls. Sometimes for the sake of convenience, the dog is put in the car first, and then goes to the supermarket to buy things as quickly as possible. On a hot summer day, it only takes a few hours to kill a dog in a small, enclosed environment. If it's in the sun, maybe it's time for you to come back and buy it quickly, and this dog can't do that.
