How do you use the obstacle course with your pet?

To be honest, I never used it...

I don't. There's no point to it in my opinion.
But if you are asking about how to do it as in the action itself, you just need to click on the obstacle object you prefer and options will come up to do it with your dog.

I tried this out a couple of times, it was ok, but not something I plan on doing again. The dogs ran the obstacle course just fine, and afterward got a popup that said how they did on a number scale. I just clicked on where I wanted them to start and they ran the whole course, they also had some training before I had them do this. That is all I can remember.

Gosh, when I click on one of the obstacles nothing comes up for me, but maybe I need to train the dog first in something, i’m Not sure what though.

I tried with two sims, you just click on one of the obstacles.

Whenever i try to use the obstacle course, the dog only uses the first obstacle.

I used it once. I've not done much with the pet training aspect in general.

The obstacle course is currently broken. It's a known bug.
