I was taking my pug for a walk this morning when he stuck his nose in a bush and started wagging his tail. When he backed out he had a live, injured bird in his mouth. He was trying to crunch it and eat it.
Thinking it might be diseased, I made him let out of it and pushed it back into the bushes with my foot.
Later that afternoon I took him for another walk and saw the same bird, awake this time, but hopping around apparently with an injured wing. Since it was hiding in the bushes I didn't bother it, but Mickey the pug was straining at his leash trying to get it again.
When I looked on Google, many people were posting, "My dog ate a bird!" Apparently it's normal behavior for dogs to eat injured and dead birds.
He didn't even try to share it with me, the ingrate.
