I never thought of taking my dogs to the market.
For one thing oldest is a butter thief and will snag anything edible off the table or counter if he thinks he is unobserved. The 100 lbs “puppy” would happily turn over a table to get it’s contents within eating range. That’s why they “own” the back yard. They will not be going to the market or any other place that sells food.
Private businesses can set any rules they like and private individuals can always vote on those rules with their feet.
However the retractable leash is the one item most misused by dog owners in public places by the “oblivious” people who, even without their dogs, wander trance-like in public places and businesses blocking aisles with their carts, standing and chatting in doorways and crossing streets without looking in either direction.
Seattle is full of them and I suspect even some of you might recognize yourself if you look back over your weekend strolls.
