A working dog got to be steady around any stock , sheep are lambing now and any kind of stress can make them loose lambs so having a brainless jook running about is bad news ,my 3 walk sheep fields most days but once lambing starts I don't exercise them any were near sheep and not because they go for sheep but to stop the stress the sheep must feel when 3 wolves come plodding towards there lambs ,
same with any stock ,you have to think of how the cattle going to react not just your dog ,
best thing for a pup is to put it in a pen with a ram ,soon have respect for them ,
