@donc I live in Ohio, and have one basenji-ocean experiece:
Years ago my husband and I drove to San Francisco, up the coast to the Basenji National in Oregon.
On the drive up we walked the dogs on a beach, no people around - perfect for walking them on a leash. When they got about 25 ft from the water's edge, they made it very clear they were going NO closer.
We finally figured it out - there was seaweed, or whatever it's called out there, all over the beach and it looked like the snakes they'd encountered in our yard.
Ohio dogs - go figure!
Sky Hunter, are you a character? I've heard, and found it to be true, that tris are characters - but fun!
