Only plan I have now is either stands and use them as side speakers (which I don't really like because I too have a large dog)
Use the BT-77 mount (http://www.amazon.com/B-Tech-BT77-Ultragrip-Loudspeaker-Black/dp/B004DCAOHK). Its a little pricey but apparently its very high quality.
The annoying thing is Newegg's description of the 45b's...."The 45B mounts on the wall, or on stands (available separately)." I naturally assumed it had some sort of wall mounting capability.
FWIW, a lot of folks have used these to wall mount their 40's/45B (and similar book shelf speakers). Being able to angle left and right and down could be advantageous for good set up. Also the monitor 35B's/30's do have a key hole slot on their backs for wall mounting.
