Yes!!! Chip goes INSANE! Let me see if I can list the things he barks at.
walkers
canes
crutches
snow shovels
plungers
mops/buckets
vacuums
brooms
tray of the crate
clothes rack
lawn mower
weed whacker
my guitars
etc, etc, etc, etc.
In fact, here is a video of him going insane at my guitar. Please ignore my house... we were getting ready for a yard sale and I stopped to attempt to practice for a bit.
