I understand what you mean when you say some dogs are more aggressive than others. Although my family kept numerous dogs when we were small, in adulthood I decided not to have any. I did relent and purchase a dog for my kids, but we eventually gave it up due to allergies.
I was shaken hearing about your encounter. I've also had horrible encounters with dogs. I have nothing against them if the owners obey rules and keep them secure.
Thanks for sharing your experience. Take care.
