We've had a lot of dogs over the years. The dogs we've owned are a part of us, from great to small. S tier - the dog had a profound effect on you. You think of them often and have many stories about them A tier - you love them, miss them, and still think of them from time to time B tier could be a lot of things, from just a few fond memories to funny stories. Sure you loved em, but it didn't break your heart when they weren't around anymore C tier - mostly neutral feeling with a fond memory or two D tier - you either barely knew them or they were just kinda there in your eyes Never Knew Em - self-explanatory There is no F tier because there's no such thing as an F tier dog
