Fin is our 4 year old fancy bearded dragon that’s usually looks healthy as can be……but for the past 3 weeks he’s been gasping for air some (taking deep breaths that aren’t normal which has gotten much much better) and what we thought was normal shedding has become puffy, pink, swollen, and sheds around his mouth? I’ve seen people refer to mouth rot, but not sure what it is exactly and how we can get rid of it if he does? I’d like to find out the cause so we prevent it from happening again if possible?
