I have a 16 week old dachshund/chihuahua mix, he's been with me for a little bit more than a week now. He usually barks a bit when I first put him into his crate, but then he usually settles down. The problem is in the morning. He's finally been sleeping until the time I want to wake up, but as soon as he hears me getting up (he sleeps in the living room) he starts barking. How can I stop this? I want him to instead wait quietly in his cage when I wake him for me to let him out. Otherwise he's begun waking up the entire house when we wake up for his morning bathroom trip.
