Dublin is my co-pilot most of the time... He's a boxer and he's deaf so I can listen to my music as loud as I like [emoji2] When he rides shotgun he wears a harness that is attached to a device that hooks to both the harness and into the seatbelt lock. You can find them cheap on Amazon. I had to replace the nylon with metal chain, as he chewed through the nylon in a matter of seconds... Rascal!
Unfortunately, the brown furry one nearest, Bailey, just recently passed away after riding shotgun for 12 years. His buddy Ignacio & I miss him terribly.
