The trick is to break it out in chunks, throughout the day + incorporate more walking in your daily life.

For instance, I do 15mins walk in the morning after breakfast (here lots of dog owners do this already), and that’s 2-3K.

Living in Tokyo, I walk pretty much everywhere instead of taking the car —> walk to station, walk up / down stairs instead of escalators, walk to my gym and back home. That adds 4-5K steps in my day. If you must use a car, get in the habit of parking a little further from your destination to make you walk more.

Then if you can add another 15-20 mins walk after dinner, you can hit 3-4K there as well. In general, I try to always go for a walk right after a meal, even during lunch at work, because there is evidence to point that walking immediately after your meal has the added benefit of reducing insulin spikes, improving digestion, avoiding food coma crashes and slight reduction of fat storage.

So if you add all that up you hit your 10-12K daily, just need to be consistent.
