My grandmother and other family members had farms at various places. Cows are more aggressive than bulls sometimes if they have young calves at foot, and it is especially important NOT to walk between the cow and the calf. That spells danger for the calf and even the most placid of cows will take fright and try to get to the calf directly. Secondly we had had many good and decent walking groups who behaved well but the most important thing that anyone walking through fields with stock in them, is to be aware that if you have a dog with you , it is a different kettle of fish and cattle with young see dogs like wolves and a threat. Sheep can lose lambs just out of running away from the perceived wolf/dog. The most important thing to remember is , if you do have to cross a stock field accompanied by a dog that if there is any feeling of being threatened by a single animal or group is LET THE DOG GO. The dog is more of a threat to the cow than you are, and the majority of dogs can run a darn sight quicker than a human, and faster than the cows too. so in an emergency let the dog go , and get yourself as quickly and calmly as possible out of the field. Dont run, in case you might trip, dont shout , just move as fast as possible. In the meantime the majority of animals will be more concerned with the dog and then if it is well trained, you should be able to whistle to it and get it to come to you. All of the children involved in any farming area where we were , were taught how to behave round the animals. Whilst I understand that a dog is a loved pet, it is far safer to let the dog take the attention and get yourself safely out of the field. But I must say, I have seen so many badly trained dogs being allowed off the leash, chasing pregnant sheep on the hillside , very close to where I lived, and stupid people saying things like , I thought he could have a run up here, or he has never behaved like this before. 3 years ago a local farmer lost more than 10 lambs and 2 ewes died , because an a badly trained or not trained at all german shepherd dog ran amok and the owner said he was usually very good. Personally , even though we had various dogs on the farm and at home I still would not chose to take a dog on a long walk in the spring time on farm land when there are young stock about. Life is tough for us all at the moment and those lost sheep and lambs represented a great loss in income to a hill farmer as well as the fact that he was trying to build up his flock with better quality sheep and so it was not just money lost but 2 of his best ewes from the good lineage. The greater amount of walking groups have done their homework, and have leaders who will have thought about where they are going and prepared an alternative route or a way round the farming areas even if it means walking on a road for a short distance. The countryside is so important to us all as we have realized with the covid situation. Let us hope that this year we may enjoy the pleasure and life affirming scents and views to cheer us. Well at least little by little we have a few more minutes of daylight to enjoy. Happy walking to you all
