Hmmmm....interesting. Do not really know what to make of this behavior. Usually I attribute conduct like this in dogs to to dog's age. It usually happens with juveniles. But this dog, at 4, is not that young. Stress perhaps? That causes behavioral disorders in dogs, so does extended periods of confinement to a small space, especially for a large dog like a husky. Don't know though. Maybe the dog just liked the thrill of the hunt. It'll be also interesting to look into the background of the dog to see if it had any wolf mix in it.  

It's not the dog's fault, it's dog owner's! Dog's trend to reflect their owner's attitude. You should see what my dog is like in front of a mooslim during the holy month of rama dama ding dong!!!

Dogs are domesticated wolves and one of the many valid evidences in the argument FOR evolution. Once in a while, the evolutionary chain breaks loose.....

That's the thing though COP. Dogs have long been domesticated. So this type of behavior is quite unusal for them. Plus, one thing that people need to understand is that predatory animals (such as dogs) even in the wild, do not simply attack prey because they can. That kind of act needs cunsumption of energy and calories, which is hard to come by in nature. Because of that, animals don't just go around and attack other animals and rip them to pieces because they can. Wild animals attacking and eating other animals is usually done when the predator is hungry, which this house dog presumably wasn't. And there are signs that the dog wasn't killing the other animals for food. The article says it was just ripping them apart. So, there's some other underlying reason for the dog engaging in this kind of behavior. 

I’m relatively familiar with huskies. They are “working” dogs and need to run around and exercise every day and get their energy drained. If they are kept in the backyard all day, they get frustrated and agitated and might do something out of character. Also, the wolf DNA is very strong in them. They are the ultimate pack canines with alpha male running the show. If you take them to the wilderness for a while and let them do what comes naturally, they lose a little bit of their domestication.

Difinitely a possibility. But in this case, this dog supposedly had free access to the outdoors, which is how he went on his killing rampages on multiple occassions. Strange case. 

PS- I misspelled consupmtion in my earlier comment. Hitting the keyboard too fast. 

All valid points. Hard to predict the behavior of any living thing based on "traditionally expected behaviors", it seems. Just look at the way some humans behave such as serial killers, arsonists, or just plain ordinary folks who suddenly "lose" it.

Always refreshing to see other topics discussed than the usual negative remarks.
