LEARN ABOUT THE BREED
For starters, the Siberian Husky is not for everyone. They require an active home and a good sense of humor. One of the biggest aspects of the breed you need to remember is that the Siberian Husky was bred to run for miles and miles and miles. The breed came to fame from the 1925 Nome Serum Run where 20 mushers and over 150 dogs transported life-saving diphtheria antitoxin 674 miles. Seppala's team of Siberians ran nearly 100 miles over sea ice, in a blizzard, and in gale-force winds to help save the city of Nome. The heart that allowed Seppala and Kaasen's Siberian Husky teams to persevere and save countless lives still very much lives on in the breed. Please, take a moment to think about the strength, perseverance, intelligence, athleticism, and will to not give up that lives in this breed for them to be able to accomplish that remarkable feat. They need an outlet to avoid becoming destructive, and that outlet needs to be more than 1 or 2 walks around the block per day.
Siberians are an incredibly smart breed, but often not the type of intelligence prospective owners are looking for. A Siberian's intelligence derives from what I mentioned above: their survivability. The intelligence of a Siberian Husky is that of a dog who is able to question things. This is often mistaken as stubbornness, to which I disagree. A Siberian has to be smart enough to make their own decisions in life or death situations, but that also means they're smart enough to make their own decisions in less strenuous circumstances. If they don't want to do something you're going to have to convince them why they should. A strong bond with a Siberian of partnership-- not mere ownership-- is needed for a successful working relationship. You must earn your dog's trust and reliability with consistency, firmness, adequate rewards, and perseverance. Without these skills as a trainer, a Siberian Husky will happily walk all over you. Even as a puppy, you must set strict boundaries so your dog learns young what the rules are.
Siberians are a primitive breed. They were bred from Chukchi Dogs brought over from Russia. Being a primitive breed, you will find they have very innate instincts such as digging, killing small animals, and running. These are difficult (and in some cases impossible) to train out and I recommend that if you would have a problem with your dog digging craters in your yard when unsupervised, killing animals like rabbits, birds, squirrels, and even stray cats, or not being reliable off-leash that the Siberian Husky is not the breed best fit for your lifestyle. On this note, I recommend that your Siberian never be off-leash when not contained in a strong fence. I have seen the best off-leash training fail and it's not uncommon that the result is death.
Simply put, a Siberian Husky is not a guard dog. My dogs rarely even bark when someone is at the door. Every person they meet is their new best friend. They will not protect your home, if they could they would open the door for anyone standing on your front step for a belly rub.
Lastly, yes, the breed does shed. Profusely. You will be brushing out your dog or pulling tufts and ask yourself "where is this all coming from?" Some Siberians shed twice a year, but many also shed year around. You will breathe, eat, drink, and accessorize with dog hair, it is inevitable. If this sounds like too much for you, this breed may not be suitable for your lifestyle.
