The dog vomits at night and is fine during the day. It may be caused by eating too much at night or catching a cold. It needs to be judged based on the dog's condition. If the situation is serious, it is best to go to the hospital for examination. Try not to feed your dog after six o'clock in the evening, because if you don't exercise at night, you will easily get indigestion if you eat again. This can also prevent your dog from defecating at night. Try to prepare a kennel and blanket for your dog, and don't let your dog eat. The dog sleeps directly on the ground.
