Dog Hair!! Go to a groomer and ask for the dog hair they shave off. fresher the better. put it around and in the bed. It has worked for me for deer, hoppers and coons. I renew the hair each week. i just rake what I can of the old hair and toss it and then put out new. After a while they stop coming around. Just one thing that works for me.

Thanks for the idea but I have too many iris for that and more coming...I'd need to shave 50 long-haired dogs each week. ;)

Fencing. Dogs. You can try a motion-detecting sprinkler. I bought two, and they work well on goats.
