This is the exact conversation I have had on many occasions!! The last time I took Jax to the pet store it took me 10 minutes to get in the door and to my destination! I would like to get him a shirt that says "I am a cane corso". lolWhat I've gotten a few times is:
Them: "What breed is that?"
Me: "Cane Corso."
Them: "My friend has a CAIN Corso that looks kinda like that."
Me: "They're the same breed, just a different pronunciation."
Them: "No, I think a CAIN Corso (is brindle/larger/doesn't have cropped ears)"
Me: "... Okay"
I think folks would rather make up a new breed than admit they've been pronouncing it wrong!
