no one's scattered lambs or run un stockbroken dog's through sheep.
you are the one quoting running a dog. every day walk is a lot different. no one has scattered lambs or purposely run dogs through sheep. there is no need for a lockdown, no one would want to be within 2 metres of you you cantankerous cnut.
OK I will do a risk assessment next time. sheep half a mile away, check, road 100 yards away check, cattle and a resovoir 2 fields, away check. you would never let a dog off it's lead.
I have had a few stock breaking came naturally no problem. had others I have had to really work hard with a young dog to get it bomb proof seems all dogs are different.
mine ran a big rabbit on a mooch last week off winter wheat and through a field of sheep. they scattered away dog never even looked at them even on her way back, but I have no doubt a farmer would see it totally different.
can of worms mate. some will tell you to leave her and it will be fine. others insist you can't do that. personally good practice (keeping things spotless) she will be fine left unmated.
little dog found it this morning only 3 eggs in. thought it a bit early but it will lay more and then start sitting. she found another a month to the day later couple of years back.
