I had one as a kid, we kind of grew up together, a sweet fella, I was disabled so I'd walk him with the pedal go-cart I had or on foot, I'd always let him off the lead at a certain point in the walk, he'd go do his thing, depending on how energetic I felt depend on the size of walk he'd get.
He'd always stop at the normal turn back point if I kept going as in a longer walk, I'd get the "Are you sure" face before he'd take off again.
There was occasions where I'd land on the deck on the walk round , he'd react by looking round and running back and literally him standing over the top of me, it was a quite a job sometime persuading him that it was ok to let strangers scrape me off the ground.
He wasn't entirely blameless, he'd get excited sometimes if he saw someone we knew and I was holding him with a lead, he'd forget about that bit, and yank me over.
Every day I'd come out of school and see him at the gate, more often than not he'd come himself.
I wasn't popular at bath or wash times I'd end up just as soaked as he was, he'd shake the water off. We fell out at those points.
Trips the seaside he'd go absolutely mental, he'd behave like a excited puppy despite being a age where he should have known better
We got him when I was just 4, , he died of cancer when I hit 19. My first experience of death at the that point, a very difficult and painful one.
