I've been stumped as to why my dog screams - and I mean loud screaming like she's being tortured - while riding in my MY. This is not something she did with our ICE vehicle nor the 2014 Model S. It occurred to me that there might be high frequency (outside human ability to hear) sound that is painful for dogs - or at least her. It's just a guess and not sure what a solution might be. Any others noticing dog discomfort while driving with them?
