The lady brought home a six month old Malamute pup that's the size of a darned horse. It's affectionate, but a little dumb. Is the breed (in general) a little dumb and stubborn as pups? Are they easily trainable? Do they make good dogs to alert for bears, or as a general guard dog? I'm a little uneasy about this 10+ year long commitment, and want to make sure it's the right breed before our breeder imposed trial period expires (two weeks). We'll be out in the bush for the entire summer, and the dog does listen well and doesn't run off, so that's a big plus.
