Puppy used to sleep through the night, now won't
I have a 20 week old Maltipoo who I've been crate training since getting her at the beginning of June. She took to the crate very well, but like any puppy, woke up every few hours to potty and such. She and I moved out of my parents house, and not long after our move, she started sleeping through the night (let's call it mid-July). I was ecstatic! We got on a great feeding schedule that I knew was going to work well with my work schedule. Well, about a week and a half ago, she started waking up earlier than normal. My parents and I thought maybe I needed to give her a touch more food because she seemed to be starving when she woke up. Changed her food amount, and she's still waking up way too early. It's getting earlier and earlier every day. She's only sleeping for about 5 hours a night! I try to let her cry and bark herself back to sleep, but I live in an apartment, and I worry about disturbing my neighbors. Not to mention, she very rarely goes back to sleep. She will cry for an hour straight, until she sees me get up. Then she'll get quiet, and only then will I let her out.
I've always put a blanket over her crate, and she's had a stuffed animal in there with her since day one, her Buggie. I don't know if she's doing this because she's learned if she wakes up earlier, she gets more time with me (I'm a teacher, and I've been spending a lot of time at the school trying to get ready for the school year), or if something else is going on. It was suggested that I let her sleep in the bed with me, but she's nowhere near housebroken enough to do that. I would appreciate any and all suggestions, because school starts next week and I need my sleep!
Thank you!
