Nice pup. I was out with friends at the J Street marina in the late 70s. One of the regular attendees showed up with his Great Dane. 250 lbs of pup. The dog had his own room at home and rode in the back of the pickup truck between home and the marina. At some point he acquired a saddle and his son rode up and down the beach on the dog.
My 1st wolfhound rode in the backseat of my Vega. Once on the highway, he knew I couldn’t discipline him and would squeeze into the front passenger seat. Of course he didn’t fit, so he’d be half onto my lap knocking my shift out of gear. Always heartstopping at speed. I can still feel the weight of his head on my shoulder.
