If things go well with the initial meet-up, let your neighbor know you’re interested in meeting up again! A date, time, and place can be set up on the spot or afterwards when both parties are more sure of their schedules.
Don’t be afraid to ask your neighbor if you can hang out with their dog, even if they didn’t ask. A lot of times owners may feel like imposing on you – just let them know you would like to hang out with their dog!
