Yeah it would be great to trail run with your dog. But guess what. If your dog can trail run, that probably means it NEEDS to, EVERYDAY, otherwise it will TERRORIZE you. Be real with yourself. You want a sentient stuffed animal. Get a dumb little puff ball dog, you won't regret it. They've been bred for centuries to be the best at Being Cute and Sitting On Your Lap.
I love dogs. I love seeing dogs in cafes. But I do not want to hear your shih tzu bark at ear splitting volume every time somebody enters please leave that dog at home
