We only have the little red squirrels around here and one guy competes with the Blue Jays and crows for the shelled peanuts the wife puts out. My Springer spaniel loves to watch him running along the wires strung from the power poles.
I have a video of the squirrel jumping from our deck to the little bag of bird seed made into a ball with bacon fat, hanging from a tree branch. It spins when he landscape on it but he gets what he wants and then he jumps back to our deck. No sign of him attempting 'break and entry'.
