About to leave the puppy alone at home

Good afternoon everyone,

I have an 11 week old Samoyed, and so far a lot of things are going well. He is crate trained, doesn’t cry anymore when I go shower, isn’t too hyper either and listens a lot. He is also potty trained at like 95%.

For the first three weeks, I had the luck to bring him along with me at work. But he’s getting older, and I want to make him used to being home alone for a while.

I’m afraid that he’s going to soil himself when I’m gone, or bark non stop and be anxious. He has a playpen, and my plan is to feed him early, walk/exercise with him and make him active a bit before leaving. I plan on coming back during lunch.

I’m going to practice over the weekend, but it still makes me feel anxious. I’d like to know if you have any advice to give me.

Thank you 😊
