Do you know anyone who has used these harnesses, @snowbunny ?
I think
@Emily might have tried the Sleepypod? When I do use a car harness, I have Allsafe ones which are tested, but to a lower standard. The dogs have more movement in them, can sit up, lay down and turn around. All that comes at a trade-off with the safety.
I don’t think any safety tested car harnesses will double up as walking harnesses; they’re designed for two very different purposes. The docco says you can use the Allsafe one as a walking harness, and even has a separate attachment point to do so, but it’s too bulky for me.
Other ways might be legal as far as restraint goes, but there are two things I consider: is the harness designed to stop my dog becoming a 20+kg projectile that would cause grievous harm or even death to anyone in the vehicle in the case of an accident; and would I consider it an adequate way of restraining a child? Attaching a tether to the collar makes me itch. Even moderately sharp braking without any impact could cause serious injury or death and I know I couldn’t live with myself if I were the cause of that.
