It's my understanding that the passenger side airbag can be disengaged. I have also heard though that the seat senses if there is weight on the seat and if there isn't the airbag will not deploy. What I am curious about is, if this is the case, will my 8-pound dog be heavy enough to cause it to deploy in an accident? The reason I ask is I just ordered her a car harness to wear when I take her places and I'm trying to figure out the safest way for her to ride. I used to ride her in a crate but from what I read this harness is safer. The airbags will be a problem though if they go off. Any input would be appreciated.
