My situation is this my puppy was listening to me when he was sick. Now that he is fully healthy he has stopped listening to me. He will run around at 12am normally when he usually goes to sleep at that time. He will bark in the middle of the night and I just am not sure what to do. He is also very bitey and I use a toy, food, treats to make him stop biting me or objects that I don't want him biting. He takes the food or treats or whatever I use to distract him. After 5 seconds he goes back to what I don't want him biting. It is beginning to frustrate me.
