Siberian Husky
4
My family has had Siberians (7 in total) for years. They're a great breed and at this point it's hard for me to imagine having any other breed of dog.
PROS: They're generally quiet (don't bark much at all); they're VERY clean (just a couple baths a year and no doggy-smell); they're biddable and trainable (and usually food-motivated); they're funny and expressive; they're even-tempered; they're sociable and friendly around people of all ages, including strangers, and they don't usually have dog-aggression issues; they're adaptable and resilient; they regulate their food intake and really don't eat much, despite their size.
CONS: They shed A LOT -- this really can't be stressed enough; they can be stubborn and willful; they can't be trusted off leash and they love to run, so an unwatched Sibe can run away quickly and easily; they have a strong prey drive and cannot always be trusted around cats and other small critters (domestic and otherwise); they need a strong handler who understands the breed's temperament and dogs in general; they're known for being a hole-digger and an escape-artist.
NEITHER PRO NOR CON: They don't bark much but they do vocalize, called a woo-woo. Some Sibes will howl. (The woo-woos are pleasant; the howls are not.) They have NO guard-dog instincts whatsoever and cannot be relied on to protect people or property. They require regular daily exercise, although nothing outrageous, and an opportunity to really stretch their legs at least once or twice a week. They require regular grooming, but nothing more intensive than a weekly, 10-minute brushing session. (You don't have to shave this breed and shouldn't ever do so. They'll cost you next-to-nothing for grooming costs each year, but you need to have a good vacuum.)
This is a breed that can be a GREAT companion, but you have to be willing to put in the work to ensure that your dog is exercised, trained, stimulated, and socialized. This is NOT a breed you can just bring into your home and put forth no effort and expect to have a happy and peaceful addition to your family. Also, this is a very pack-oriented breed that NEEDS interaction with its humans, even if that's only one person.
Above all, bear in mind that Sibes were bred to be independent thinkers. Its in their genetic programming, and you can't dominate or yell it out of them. If you keep this in mind and aim for a high degree of cooperation with your Sibe, you'll have a happier relationship. Sibes want to please you and they're biddable, but they are not a slavishly obedient breed of dog.
