cats won't generally eat and eat and eat. dogs will. not to mention, huskies don't need as many calories as other breeds. it would not be in your best interest to leave food laying out all day. my parents have a lab and they even schedule his feedings . when we had our first dog (a golden retriever) not as much was known regarding pet nutrition and my parents left food out for him all day. he wound up being overweight. overweight doggy = not happy doggy. being overweight can put extra pressure on their joints, and big dogs already have more joint issues than smaller breeds in the first place.
i don't mean this to be rude at all, but you shouldn't really be thinking of the "easier" way to do things. if you don't think you have time to feed your dog at his/her scheduled feedings, then you probably shouldn't be getting one anytime soon, at least not until you have more time.
also, in regards to what you've done with your other dogs in the past, i'm sure you know this by now but a husky isn't like other dogs
in regards to blue buffalo, i don't know much about it, after reading everyone's reviews on here, i decided to feed luka taste of the wild. it's grain free, pretty affordable, and he loves it!
