Huh? A hawk is NOT going to attack a boxer! Tea cup poodle, maybe. If your post is a joke then fail on me but on the off chance someone read that as serious....
We have countless hawks in our yard daily. They never even attacked our chickens. (Nor 3 of the previous boxers we had ). Perhaps our 2 lazy day beagles deterred them... when they weren't inside sleeping.
You may note the raptor in the video has a tether tied to it? It is used to being fed by humans and that little excuse for a dog looked all to similar to its training routine.
Raptor are amazing creatures. Whoever shot that with a bow is a piece of dung, full stop.
If that hawk was going after my poodle the boxer would go after the hawk because he is very protective of his big brother. Plus the boxer attacks ANYTHING moving in the yard and It wasn't worth the vet bills to find out as big as that hawk was. And for your info I USED to have to a stray cat around the yard I haven't seen him since I saw the hawk.
If you google Hawk attacks against pets you will see numerous videos of hawks attacking dogs and cats. Hartselle Alabama was one of the best small cities I ever lived in where everybody knows everybody and that arrow can probably be traced to one of two stores, Wiley outdoors or cabelas.
