Paws Up is a great object interaction that we can use while out and about!
On every outing, you will be able to find many different objects to practice this on. Dogs like this trick a lot as it’s interactive and let’s them engage with the environment (but with us as “part of the picture”).

Of course, practice this inside first and then gradually advance it to different places based on your location difficulty scale (for example: you could practice this with a stepping stool in your living room first, then you take the stool to your patio, then to your front yard etc.)
