We're not sure what birds have against man's best friend, but there's no doubt they can be giant assholes when they get around dogs. Don't believe us? Just watch these birds bullying these poor pups.
Clearly, they prefer the sneak attack from behind.
Sometimes they even dive bomb from above. Poor guy can't catch a break in a public park.
It turns out birds can get very protective of their territories and their nests, which might explain why they try to keep dogs away.
We think this one just hates Chihuahuas.
Even roosters are getting in on the action. At least this pup doesn't seem to mind.
Some birds are downright brazen. This little guy ups the ante and tries to take on a polar bear!
Whatever the reason, birds seem to have a preference for aiming for the butt.
