When i was about 5 or so.. me and my mom were going to the store... Sitting on a bench by the door to the store was a homeless man and his dog. It was a male rottie named Buddy... and yes i remember this dog, and the man clearly. Instead of giving him about 5 dollars like normal we gave him a 20. I petted the dog and he was as sweet as can be. Im nto too sure about the question but i thought i would share this.... i guess it could be a good thing since it could be like protection? im not sure but its a good question
