This keeps out a 150 lb mastiff. It's incredible stuff, I got it at Lowe's. I think the mastiff has jumped on it 3 times with zero damage to the fence. Only thing it hasn't kept out is copperheads! My DH almost got bit a few months back.While turkeys can easily fly over an 8' fence, they are more likely to pace back and forth beside it. As long as there are no enticing tree branches close to the fence it should keep them in.
What they sell as deer fencing here would not keep a dog out since they could easily rip right through it.
