It could partially be a separation anxiety issue.

My Shiba is also a guard dog so he will alert and bark when he sees unexpected things happening or when people come to the door. I come to check things out when he does this, and thank him for the warning. Usually he stops barking when I come over. If he doesn’t, then I just give him the Quiet command (previously trained). Then I redirect him into doing something else with me – e.g. play a game with him, or get him working on chewing his favorite toy.

My Sibes will sometimes bark because of excitement. When I take them on shorter walks, they are more likely to get over-excited at home. What seems to be most helpful is to keep them busy with sanctioned activities – longer walks, work for all of their food, play sessions, etc.

What helps a lot with my Siberian Huskies is to provide them with a lot of activity and exercise. When I take them on shorter walks, they are more likely to get vocal in the backyard, mostly alerting to noises they hear from outside. Now I make sure to keep them busy and I also make them work for all of their food.

Are there particular noises or smells that set your dog off? What triggers the barking?

Another thing that helped with my Sibes is to first put the behavior under command control, e.g. train the Quiet command. Then we can slowly desensitize our dog to her bark triggers in a positive context.

With Sephy, he really needed some off-leash play time. He really loved to play with other dogs. Some things I did with him before he got all his shots -
1. Puppy class. I enrolled him in puppy class where we did both commands as well as short play sessions with the other puppies in the class.
2. Puppy play groups. There is a daycare center in my area that does supervised puppy play groups. They check to make sure that all puppies that come by are current on their shots.
3. Puppy play dates. My neighbor at the time had a really awesome puppy so I would go fetch her as often as I could and have supervised one-on-one play sessions at my house.

Here are some other things that helped with Sephy when he was a puppy -

Shiba puppies do take up a lot of time and attention though. If a Shiba puppy is not a good fit for you, consider re-homing her through a rescue. She is still very young, so the transition would be easier for her.

Good luck. Let us know how it goes.

Even though you may want your dog to stay home most of the time and don’t plan on entering it in contests or competitions it’s important to train the dog properly.  Even house dogs need to have some obedience and other training, to make them the best d…
