Agreed. All animals have different personalities, as are people and their relationships with their pets.
So that there are no misunderstandings, I was merely stating how I trained the three dogs that are around my flock often, so that OP and anyone in the future would have another example. Discipline was implied when I stated that I’ve been training my dog since she was young.
All three had different personalities and they didn't learn at the same speed. The two dogs that I do not own, use to chase my birds and did not listen very well initially, especially the younger one. As stated earlier one has even killed 2 of my pullets becoming her chew toy. All three were salivating during the first several introductions. Two kept lunging at the birds that were in the coop. All of which was corrected on the spot. That all stopped once they learned I was in charge and the flock belongs to me.
Needless to say, common sense dictates.
