Eagles do take dogs. I grew up in Alaska and every year we would hear a story of sightseeing retirees letting their lap dogs out. They would get snatched by an eagle. Eyewitnesses would say that the poor dogs were screaming for several minutes, before they died.
Be careful if you have a little dog.
Once one went after a 2 year old girl, the parents were able to chase it off. Everyone assumed it didn't realize how large a two year old was. (Looking down- just saw the top of the head)
A couple years ago I had an eagle sit in a neighbors tree watching my yard. The crows took care of it after a few minutes. I don't think its ever came back. I hope I have enough trees and brush to provide sanctuary for them.
Also if you want to see eagles go to a landfill, that's where we used to take houseguests.
