I worry a lot about you riding with a pup. It's usually a lose lose for both parties. I had a friend who had a racing-rescue greyhound. The only way she felt like she could adequately exercise the pup was to take it to a local baseball diamond and have it run in huge circles. they're usuallyenclosed, so the pupper couldn't escape, and it meant lots and lots of running for the dog - and not for her. You'd have to be super conscientious about the shit though. No one want dogs shit around. I hear ya on the mask thing. Allergy season is weird... and every little cough or sneeze is making people around me nervous. Ugh.
She needs big active exercise. She needs to run. And I'm just not capable of that any more. If she could be trained to run with a bike (a big if, but not too hard to do) then she could stretch her legs out and tire herself out, as well. Would be good for both of us. And heck... an e-bike would be generally useful for me, as well.
