Flo back some years ago the same thing happened to a Boston terrior on the Dr Pol show. They brought him in to Dr Pol because of the sneezing and acting like he was having a hard time breathing. They looked up his nose with a camera and saw something green so used a long tweezer to grab the green thing which turned out to be a long blade of grass. He said it was long enough that it was hanging down in the dogs throat. Dr Pol also stated he's never seen anything like that before.

In Dr Pol's case, he didn't charge them to pull the blade of grass out of the dogs nose
