OK, just to clarify… my housemate would also like to sleep in till at least 6:00, and only gets up earlier because the puppy is barking. The only things we’re doing that could be waking him is me starting to shift in bed, or possibly my roommate going to the bathroom and back to bed. He might also be hearing the cats beginning to meow for breakfast, but generally, all is quiet in the house until the puppy starts to fuss and bark. It’s not until Chill is released from my room that he and Castor race downstairs and are let outside. I believe my roommate takes that time to get my old girl downstairs, and to feed the cats. She then lets the boys in, and sends Moxie out (Chill’s been humping her lately so we no longer let them be in the yard together without us being out there with them). Once everyone is in, I believe my roommate lets the dogs hang out in the kitchen and living room while she does the morning chores (cleans litter boxes, washes dishes, watches TV and tries to wake up). After about half an hour she’ll feed the dogs.I'm saying that your housemate moving around, letting dogs out, feeding them + is creating the whole routine where the dogs know 5-6 AM is time to get up, run around outside, etc. And the barking is getting encouraged as well, because pup barks... and housemate pops in and give them what they want.
It would be better if the housemate who I assume is getting up at 5AM or doing something that is waking the pup.... could just let her outside with the other dogs a little earlier, and feed them.... and then either bringing them back to bed, or just letting them hanging out in a dog-proofed area together (assuming they don't playfight/wrestle when loose, I wouldn't leave active playing dogs along together, especially if one is a puppy) while they go on to work or whatever and you enjoy the remaining 1-2 hours or whatever of sleep.
Just doing that on a regular basis - vs waiting for the dog to start barking and rewarding the barking by letting her out and starting her day.
In the meantime… I wake up when Chill starts barking. I do my best to ignore him, or give him an occasional “Chill! Enough!.” Once my roommate finally lets him out, he sometimes goes right out of my room, and sometimes jumps on my bed and licks my ears. 🙄 When my housemate finally gets everyone out and closes my bedroom door, I can finally doze a bit till my alarm goes off and I have to get up and get ready for work…
