>>>Rationalise it how you will, if you have lived with animals (and I suppose we all have), you see a mixture of things instinctive

That is so true. Our dog Max is a herder breed, however, he was born to a non-herding mom in the city, and never exposed to cattle in any way. BUT, I cannot take a walk with my Hubby if he decides to take the dog along because the dog will herd us incessantly.

If I fall behind one foot, he'll push me along with his head. If I walk a little ahead, he'll step in front of me to slow me down. If I get more than seven inches away from Hubby, he'll sidle up beside me and walk in an angle while pussing me with his shoulder so I am touching my husband. It's annoying I tell you.

He goes around us in circles, checks out the front, the sides, then the rear...checking for what, I don't know, but he does it.

Mind you, I wouldn't mind so much if I wasn't the one that was being pushed all the time.
