I have a recently rescued German Shepherd that is about 2 years old. We have had him about 2 months. We were thrilled that he did extremely well with our cows. He doesn't try to herd them, doesn't bark at them and seems to have a healthy respect for them if they move too close to him. He has been perfect with them, basically just ignoring them. Today, we had a calf born and now he sits at the fence barking at it non-stop. I will call him back and bring him inside but as soon as I let him back out, he starts again. This is really upsetting the mama. Any suggestions on how to handle this?
