What breed of dog has largest tongue?

It's difficult to say definitively which breed of dog has the largest tongue. There is no official measurement or record kept.

However, some breeds known for their long, floppy tongues include:

* Newfoundland: Known for their massive size, Newfoundlands often have very large tongues.

* English Bulldog: Their pushed-in faces and loose jowls often lead to a prominent, large tongue.

* Bloodhound: With their long, droopy ears and wrinkled faces, Bloodhounds have a distinct tongue that often hangs out.

It's important to note that tongue size can vary within a breed, and individual dogs can have exceptionally large tongues even if they're not of a breed typically known for it.
