Unfortunately, dogs "bark in alarm" when there's any kind of predator around. That can be dangerous ones like bears and wolves that you really should pay attention to, but most of the time it's just annoying ones such as birds of prey, foxes, or one of the small ones (pole cat, pine marten,...) that are depicted like rats.
It's extremely annoying when an owl gets caught in a snare a minute into starting to bang on an elk hide, having the work interrupted every few minutes due to the blasted dog barking...
