Biscuit makes a funny little noise out of his nose when I am riding. The first time I rode him to try him out I told my cousin "what is up with this noise? I don't want a horse with issues". She said he was fine. He is fine but he does make this little huffy puffy noise - especially is he is annoyed or a little nervous. I ride with cousin all the time and she went on a camping/riding trip recently and just cracked up because HER horse was mimicking Biscuit's noise! Her husband said "what is wrong with Elan?" She said "he is missing Biscuit!"
