Drone Vs Ram
Occasionally a ram will make a bit of a stand against a single dog if he's out with the girls but usually not for long, two dogs which many shepherds use are normally too much for any ram unless it's been on too many psilocybins, on the other hand floating your expensive drone a foot away from a recalcitrant ram will provide you with many spares for the next one you (have to) buy.
Those things can get to be quite snotty.
The above based on a little experience on a friend's farm in Wales.
