I'd jump out of the car and not have it on my conscience, I figure momentum killed one of them and I was not in control of the vehicle after I bailed. Chances are if I were going that fast, it's not in my car.
Seriously though, I hate dogs but I wouldn't swerve into it. I'd report it, kick most of it off the road so others don't make a mess, wait for the road kill cleanup crew holding my nose and be on my way. I've been through this before but it was a cat and a city bus, I was walking on the side.
The meaning of life is curiosity; we were put on this planet to explore opportunities.
