is this bunny damage?

is this bunny damage?

the shrubs in my front yard used to be nice and full and round, with one being triangle shaped. after this winter they arent anymore. the bottom foot of all of them is dead, looks like its been eaten away. is this bunny damage and is there anything i can do to help these poor things? Photobucket EDITED TO ADD: Photobucket a picture of the shrubs before winter, showing the lower branches that are now completely gone ETA: looks to be cold damage rather than bunny damage. TO THE MODS - TAG REQUEST: um, how do we REMOVE tags? it wont let me remove them they way my own journal does. i originally wanted you to add zone 4, but read the post on how some tags werent showing up but were available. now i cant delete the 'to the mods' tag.
