Sharing my lunch with a new friend

Today, after getting my residence permit, I went to Porta Palazzo to bought a piece of Pizza for my lunch. I went to enjoy my lunch in a park in between the Duomo and the Porta Palattina as the weather today is quite good, even now it is the winter. While I was almost half of my pizza, a man with two dogs arrived in the Park too; one of the dog came to me, by shaking his tail; I knew that he also want some of my lunch. I asked to his owner for permission to give the pizza to him, and he replied me with a smile, so I gave some of my lunch to him; one bite for him, one bite for me; the second bite, I tough him to jump up in order to get the food. He actually learned to jump for getting the food really fast, I really enjoyed the half of my pizza with him. Here in Italy, they always bring their dogs out for fun, not just to keep them at home; they give some time for them; animals are just the same to us, they also stress being always at home.

One thinking point, when the dog come to us by shaking their tail, we knew that it is coming for friendship, not attack; but human doesn't have tail so it is quite hard to know, some time they smile to us, but they are coming as our enemy.
