1. When I was in high school I whole heartedly bought into the popular televised 'alpha rolling' approach to dog training. :/
2. Growing up all our dogs were always kenneled all day. It wasn't until after college I realized some dogs could be allowed freedom during the day. Felt bad retrospectively for keeping the good ones cooped up unnecessarily.
3. I used to be one of those people who would approach all puppies and let them jump all over me. Sorry past general public!
