The dog suddenly finds a small corner to lie down. It may be caused by the weather being too hot, the environment being unfamiliar, fear, timidity, fright, or physical discomfort. It is necessary to observe whether the dog has poor energy or appetite. If there are any abnormalities such as lack of energy, vomiting and diarrhea, it is best to send the dog to the doctor for treatment in time to avoid delaying the condition; if there are no special circumstances, don’t worry too much and just let the dog relieve itself.
