Alternatively you could ask the owner holding the dog.

I don't disagree that knowing the breed might be nice, but again I feel like it lacks a real-world use-case. How many dogs do I see in day to day life that are unaccompanied? None.

Genuine question, is that something we really need?

That's a lot of hardware and compute just to have a gadget that helps identify dog breeds, assuming the dog is purebred to begin with.

What about mutts? Would be cool if dog physiognomy is so advanced it could identify distinct breed percentages. Then we could apply it to humans. That would be useful!

One step closer to the app I always dreamed of:

"Can I eat this?"

Your phone can do that though. It's built into iOS, and I believe on Android it's part of Google Lens.
