One of my skinny pig boars seems to have lost his voice. I don't know his exact age but my best guess is hes somewhere around 2.5 or 3 years old. Over the last 6 months or so his wheeking has changed to become more of a raspy heavy breathing. It doesnt sound like there is phlegm or liquid in there, it sort of sounds like he is breathing through a straw - but only when he tries to wheek. Aside from that, hes a healthy boy. I weigh him weekly and his weight is stable, his breathing is clear, and he still eats and popcorns all the time like a normal happy pig. He used to have a pretty loud wheek and now its just this airy sound. Has anyone ever heard of anything like this before? I think I'll take him to the vet to get checked out anyway.
