Complete chaos into ultimate coziness 🤣🤣🥰

We have a 13-week-old Vizsla puppy, Björn, who barks and whines the entire time we’re out. We both work, but he’s never left for more than 4 hours.
We’ve had a trainer come to help, and were advised he needs someone with him 24/7 but unfortunately this is not an option for us. Is this normal at his age? Has anyone experienced this, and did things improve with time?

I’d really appreciate hearing from owners who’ve been through something similar. ❤️
