So I’ve had m pig for three years now and the only thing I’ve ever noticed is that sometimes his breathing gets really loud and I have to hold him until he’s better. Now I’ve been doing this for three years and he hasn’t ever had any trouble with anything else. I’m not sure if it’s because of something he eats or the type of bedding but I don’t think it’s a URI because I don’t think he’d live through one for three years. (Also I just figured out URI were a thing today or else I would have looked into this sooner)
