I have seen many promotions done when shelters get overpopulated.
Lots of rescued animals go into show business, so it wouldn’t hurt to have contact information for trainers.
Puppy brunch, public invite.
Toys and pets playtime, kids and their parents in a playroom full of pets.
Free pets for seniors day, half price for everyone else.
Pet Christmas stockings included free with adopted animal at Christmas.
I have seen various public activities where animals up for adoption were available to see.
I think if I were organizing, I would look for a parking lot where I could set up a pet parade, with little floats pulled by golf carts and tricycles, dogs on leash dressed like clowns,
