Remember me? I picked up my Maltese on Thursday and at the beginning he was very shy, but ever since then he's been very happy, playful, eating and going on his pee-pee pad. Because I'm trying to train him, I have him confined to one room, and therefore, for the last two nights he's been crying. Otherwise, he's been very playful. During the day he's been napping (awake one hour, asleep one hour). Now for the last two hours, he's been sleeping. I try to wake him, he seems okay, but then goes back to sleep. Is this because he's just exhausted or should I be concerned? Oh, and don't forget, he's only 9 weeks. Please help!!
