Every time my husband takes the dog on the trail off leash, he turns around and comes back,if he knows I am home. If I am gone, he walks off leash just fine, and doesn't run home. My husband can be stern, but I don't know why the dog comes back. It really upsets my husband, to turn around and poof the dog is gone. He's ready to quit walking him. The dog lags behind normally sniffing where other dogs urinate, but will come when called. Why is this happening?
Honestly, it's quite normal for dogs to have one favorite person. It's not like he doesn't like your husband, it's just that you are his social anchor and he prefers to be near you. As humans that hurts our feelings, but for a dog that is pe4rfectly normal.
One possible way around that is to play games with your dog while he's on the leash and continuing the game when he's off leash. That way he (hopefully ;) ) is concentrated on the game and not on you back home. It may take a while to break his habit and keep him with your husband.
Another thought: what happens when your dog runs back to you? Do you talk to him in a high voice like after he did something right? Do you get up and walk with him instead? Australien Shepherds are very intelligent and your dog may find the result of running back home more rewarding than walking with your husband. Bluntly said he may be manipulating you into giving him what he desires.
My personal opinion is this: if you cannot control your dog while off the leash (like stopping him from running onto the street in front of a car), then don't take him off the leash. Dogs have their own minds and some will never follow commands reliably off leash, so that's no failure or anything of yours. Why doesn't your husband finish the walk before letting your dog off the leash? Isn't a 10-minute walk at least better than a 1-minute walk and running back?
