Hi Robert. Yes, of course I remember you :) Glad to hear that Heidi’s nerves are improving. It’s amazing how an improvement in one aspect of nerves can help in another area.
I find it’s important to bring a dog on slowly in a controlled environment. Anna was introduced to horses at a gymkhana at 12 weeks old from the safety of my arms. Then came the viewing of cattle, on the lead whilst walking along the road beside a field, no fuss, no bother, I just treat the cattle as if they are not there. And so we progressed from there. At one time last season I was standing in the middle of a solid circle of about 30 sheep all stamping their feet at her. I think that because she’s yellow they thought she was a lamb.
So, what to do in Heidi’s case? First off, you must treat it as totally blasé. Totally unimportant! How is her sit stay? As you have the permission of the farmer I would leave her in the sit whilst you walk a little closer to the calves and then back to her. Without words of encouragement or anything I would call her up to heel and continue walking away. That’s enough for one day! Gradually over a period of time you go closer to the cattle. This means that you will be leaving her for longer periods of time. Each time you walk back to her you call her up to heel as you pass her and continue away.
The next stage from there would be that on returning to her you would call her up to heel just BEFORE you get to her and if you have done the previous stage enough times and she has seen that nothing has happened to you then she should not be too concerned about coming the odd couple of foot closer. Again, gradually over a period of time call her earlier and earlier but don’t attempt to call her right up to the cattle, it’s just not necessary! If she was working then the excitement of the occasion would take her closer if needed.
If you can get her reasonably happy around one kind of livestock you will no doubt find others are easier. We have cattle early in the season changing over to sheep around Christmas time and although Anna is use to most things she is always under orders around all livestock. She is either, walking at heel, sitting at heel or retrieving. Never EVER running free.
As to the book, I think it is on hold at the moment until Lucy’s baby arrives. After all, gundog training books come a poor second to baby Johnquil

Best wishes, John
