Last spring. We had an incident with a sheep attacking a dog on the lead, protecting her lambs. A small kind of dog, but nonetheless the woman involved was knocked down and all kind of tangled in the lead trying to defend herself and her animal from a rather determined ewe! My question is what should I do next year? Maybe some warning signs, maybe nothing, I just didn't know if I'd get in trouble for having an agressive sheep in a field with a footpath? Probably worrying too much?!
