I've thought about it a little bit, the "why" we do it time after time.
Aside from all the other reasons that we also get from our human relationships.
I have a theory on that, but thinking on it a bit more.
Haven't seen #Dogstr #1 & #3 in 4 months. #3 (no longer a pup) was the first to run to me when I stepped out of the car and he's also the youngest. #1 (the OG) was like "yeah dude....you good?" and went back to the porch.
I kept #2 in the car for a bit to let things settle down before I let her out.
