That is awful. Dogs are an ever-recurringnightmare for those of us with outdoor rabbits. Height on the cageshelps, as does a fence, although neither one is fail-safe.
I've been toying with two ideas: a little garden-style electric fencearound the bottoms of the cages, or mousetraps hanging from the bottomsof cages. Or clattery things thatwould get knocked over, orsharp things protruding from the cages.Ought to make anyattackers think twice anyway. Now that my cages are higher, I haven'thad any incidents lately, but I know that it's always a possibility.The electric fence idea is one I may try when we move to a "real" ruralarea.

P.S. one of my does escaped death by dog attack when she fled into thewooden sleeping box. We found the cage torn up, blood on the wall, anda shiveringIzzy hiding in the corner of the box. Apparentlyshe hit her head in panic and got a bloody nose, but shedidsurvive that attack.
