Felix,
If I had a dog that was steady to wing and shot, I would use a 160g Snuffer, but the odds of that are very, very slim. I don't want there to be any chance of getting a dog hurt so I go a different way.
I've tried a lot of combinations. I've never used any of the big Snaro type points, they seem like they would need a lot more horsepower than I have to work properly.
I've had Judos and Ace Hex blunts bounce off birds.
What I find works best is a field point with a Zwickey Scorpio behind it. I want to keep the arrow in the bird if at all possible. The bird will not get away from the dog if that arrow stays in.
