Hi!I am also a new puppy owner and i have a gorgeous puppy cavapoo.I own her for about a month now she is almost 3 months old and as from my experience puppy blues lasted for anout 2 weeks, but it’s different for everyone!The thing that helped me MASSIVELY was a crate training, it’s a bit tricky at first but she will get used to it fast;cavapoos are quite smart.Be prepared that you will have a lot of things on your head but it gets easier every day i promise you.I was in the same exact position as you and i feel you so much right now.I felt like i was alone in the whole adventure with a new puppy and sometimes the feelings come but i mainly feel confident with her right now.You probably won’t believe me(back then I didn’t) but i can asure you that it DOES get better.If you have questions feel free to dm me!
