From the BBC:
Eagle to patrol Italian airport
It’s a golden eagle that can lift 40lb. That puts many dogs at risk. The airport bought the eagle to deal with a fox problem.

You can’t believe everything you see in print.
There’s a huge difference between what a raptor can kill, and what it can carry away. The realities of physics and aerodynamics prevent these birds from carrying much more than about half their body weight.
A large female golden eagle might weigh 15 pounds, so anything larger than at most eight or ten pounds might be killed then dragged along the ground, but not carried away. Forty pounds is clearly an exageration.
The harpy eagle Colibri mentions might max out at 20 pounds, and apparently routinely preys upon sloths in the 10 pound range. She can pick one out of a tree, and carry it to a perch to consume it. But at that extreme size range, the resulting flight will be mostly lateral, and slightly downward-- not up, up, and away.
Golden eagles are sometimes flown by falconers on game up to the size of (small) deer. Again, their ability to kill something is not nearly matched by an ability to carry it away.
Regardless, attacks by various raptors on domestic animals remain quite rare. They (the cats and dogs) just don’t fit the proper prey profile.
BarnOwl, I would hardly think that shooting squirrels to appease the appetite of a bird of prey would confer much protection on your dog. Instead, you’ll end up with an habituated raptor who focuses on a specific and highly productive hunting territory. Your yard. What do you think is going to happen when the supply of squirrels dries up?
Squirrels are the upper size limit for red shouldered hawks (smaller than red tailed hawks). The red shoulder would patiently sit in your tree for hours, awaiting just the right chance to ambush a squirrel that momentarily drops its guard. It would not involve itself in any lengthy chase scenario, going round and round the tree or otherwise making its intentions obvious. But actively hunting by ambush for a squirrel that is alert and wary is quite different from accepting an opportunity to immediately take one that is injured and crippled by intervention of your pellet gun.
