If there were a machine that could only detect one disease, I don’t think that automatically precludes it from being cost effective. I could see a dermatologist buying a cheap pen-sized device that solely detects skin cancer, at least.

Maybe, but dogs (or any animal, really) require constant care in a way that machines don't, and need space and staff for boarding, exercise, veterinary care, etc.

(Unless somebody is working toward a cheap pen-sized dog...)

For better or worse, we already manage large numbers of cattle and chickens. For the most part we don't feel bad for them. Treating dogs in a similar fashion would probably not be socially acceptable. What does the use of diagnostic dogs look like at scale?
