I was riding (walking) DHorse on a public bridleway on a racecourse. (And training area for race horses) A young dog came tearing round the corner and proceeded to bark and jump at DHorse’s tail. The owner appeared and was not able to recall the dog and complained that we had surprised him by appearing around the corner..
Fortunately DHorse neither kicked the dog or bolted ( either are possible) but was it reasonable to think he should anticipate horses being around in a location like this? If I can keep 600kg of flighty animal under control why is it so hard to do the same for a 5kg spaniel?
