I asked in a thread about hawks (about 2 or 3 weeks ago) if putting clothes on my Mandie would deter a hawk. The answers I got were that it wasn't likely. Now, in this thread, I'm reading orange vests and reflective clothing might help.
I think anything is better than nothing, so my new game plan (along with always being vigilant) is to always have some bright color clothing on Mandie when we go out. I will look into hanging old CDs, as mentioned above, too. Can't hurt..may help eh?
