Please ask yourself why you want a siberian. Most people are attracted to their looks, but that's not a good reason to get one.

Unless you have the time, patience, space, and accomodations for a siberian, I would strongly recommend you look into another breed. Siberians are wonderful dogs, but yes, they can be challenging, destructive, stubborn, escape repeatedly, major diggers, and some can be quite loud if left alone for long periods. The fur never ends - the big shed is called "blowing coat" because it comes out in handfuls then, but they shed all year.

When you have the yard space, minimum 6' tall fencing, companionship for them so they aren't alone all day, and have plenty of time to exercise them, take them to obedience classes & work with them (because they never stop pushing the limits), then you stand a chance of having both a happy dog and a happy family.

From what you posted, it doesn't sound like you are ready for one yet. Maybe down the road? There are many other breeds that would be better suited to your lifestyle. I'm not trying to be harsh, just realistic. Too many Siberians end up in shelters because they were more than the person bargained for. You deserve credit for looking into this before committing - very smart.
