We have wild turkeys near us. My chocolate lab went a couple rounds with a mother turkey this spring. First couple of encounters went to the mama turkey as she was defending her babies and my dog was just terrified of her. She would spread her wings (6-8 feet wide or so?) and then hover above him. He would freak out and back away, terrified. Eventually the dog got brave, chased her off and ate a couple of turkey babies. But based on that interaction, I definitely would NOT bet on a lab taking down a velociraptor. The raptor would have gone for the kill when the dog was still scared..

Yes, turkeys (wild or domestic) have spurs. Typically an inch or so in length, up to a bit more than two inches for the biggest, oldest birds. They also have interesting beards, which can be 10 inches long!

They'll bluster and charge to defend young against a curious city dog, but will flee up to roost if challenged by a pack of hunting dogs. If you find a cornered turkey, don't try to catch it or let your dog attack: you'll probably win from sheer mass and from having predatory weapons, but you will be badly bloodied.
