I have both a dog and a backyard. Walking is far more interesting and stimulating for him than letting him run around in the back.

Have yard with dog door, it’s good for a bored sniff, and occasionally howling at an ambulance. Doesn’t come close to the stimulation he gets from the park or some active interaction. It made housebreaking easy, but that’s it

My dog absolutely hates being outside in the yard, but she loves walks and hikes. Unfortunately the nearest place that’s safe for us to walk is a long car ride away because I live in a somewhat rural area. So she only ever gets these on weekends when I’m able to dedicate several hours to it. If I were to live in a city she’d be getting a ton more stimulation daily.
