I didn't say that an incident meter measures anything other than exposure. I didn't say they were new. I said that the combination of very high quality and affordability is now more obtainable.
An exposure reading from a spot meter, old school or in the camera, is a reflected reading, as is any other type of metering done in your camera. By definition, the exposure value determined by the camera will change when you substitute a white dog for a black dog. Has the amount of light changed? No, it has not. By using the incident meter you can shoot a white, a gray and a black dog in succession, bing-bing-bing, without changing the settings on your camera, which is why I stated that it would be optimal for THIS PARTICULAR situation.
Cat- have you ever used an incident meter? I didn't think so. You shouldn't be so quick criticize things you don't understand. Borrow or rent one and give it a try. Learn or have someone teach you how to use it. Then decide, for you and everyone else, if it is an expensive encumbrance.
Why do I bother? Because "at best" the two of you have shown yourselves to be illiterate, and "at worst", imbeciles.

No need to go Trump on us. It is in really bad taste.
But you are negating one thing. Reflectance is exactly what the camera sees. Incident meters make assumptions. While it's true that most of the time, in even lighting conditions, an incident meter will provide a reasonably balanced exposure, the meter is making a guestimate at best, and using some assumptions that may or may not be true - especially regarding dynamic range of the camera or the lighting. If that dog is moving around - they usually do unless it has been provided by a taxidermist - then it can be moving between shade and sun. The exposure value will change. The incident meter will not consider extremely wide differences in reflectance - try shooting the black, gray and white dog in the same take, with the black dog in open shade, and the white dog lit by the sun. Been there, done that - the result will likely be a severely underexposed black dog, a severely blown out white dog, and the gray will be ok maybe. Reading the reflectance and adjusting the meter accordingly, or just dialing in a compensation value will always result in accurate exposures.
But only if you understand what you are doing. Based on what you wrote, you are oversimplifying things a bit and might not have the grasp on this you think you have.
Digital is not the same as film. When you underexpose negatives the detail is lost - nothing is recorded. The opposite happens with digital - it happens to the highlights. One thing is different though. Digital will record far deeper into the shadows than film ever could, and if you have a camera with very low noise, you can underexpose shadows 5 stops or more, and still get detail - it will be muddy, noisy and lacking in contrast, but it will be there. At the other end there is no reason why you have to use the exposure suggested by an incident meter. Moving the exposure to the right for any of the dogs will result in less noise in the shadows.
The best thing I can tell you is go out and try it and see if works for you. I've been doing the zone system, upon which these concepts rely, since the late 60s. I don't mess up on exposure - I nail it every time. I use reflected readings 99% of the time, and I have two incident meters. I really only use an incident meter when I have total control over the lighting, or when contrast is low to medium and even then I will tend to expose brighter than the meter suggests - but only because I want better shadows. I always use it when working with studio strobes and with speedlights in the studio as well. Again, I have total control over the lighting, and use the incident/flash meter to set my lighting ratios.
Using an incident meter with moving subjects in changing light is not easy. And with a white dog, you risk overexposing the bright side if it is in bright sunlight. Maybe you lack experience shooting moving subjects. . . .
You may not be able to get your mind around this at first, but it's worth a try. Hell, you might actually learn something new that you can use to expand your horizons and improve your photography.
Be nice, don't insult people, and you will have a better exchange of ideas, and you may learn a thing or two here and there.
