The Sims 4 Pets Question

@EeveeTinn While walking your dog, try unleashing it (as @diopter77  already suggested) and then ask the dog to go potty. After it has finished, re-leash the dog and then click on Go Home for your Sim. This should make your Sim & dog walk straight home. I just tried this with my Newcrest household. I waited about 1 minute (real-time) into their walk and after their first break or pause in the walk. The owner still got a good moodlet for taking the dog on the walk & the dog stopped asking to go on one. It took less than 3 minutes real-time from start to finish. I can't remember if this is always how it's worked in my game (I usually just use cats) or if this is something new.

EDIT: Lol oops I now see you already replied that you tried this. I was typing this with one hand (my cat is sleeping on my right arm & I don't want to wake her up) so my typing is kind of slow for this post xD
