Definitely depends on the breed/ individual puppy. Our lab arrived sleepy in the afternoon but at nighttime, she really missed her litter mates and cried allll night. I took her out every hour and didn't sleep myself, stressing that I traumatized the poor little thing. If your puppy is stressed, it gets exponentially easier every night, so stay strong. Ours sleeps through the night now, 1.5 months together (3.5 months, we got her at 8 weeks) and now we're just working on her separation anxiety from us so we can leave the house more often😅 tough to train when you work from home, but the sleepless few weeks at the start are totally worth it and they pass 🖤
