hi i hav a 3 yr old pet turtle (indian) ..he sometimes blows a bubble from his mouth..what could be the reason...what is the best kind of food that can be fed to them..
It sounds like a respiratory problem. Be sure your animal is dry and warm enough. It will still need to have warm soaks. Just be sure the substrate is not damp.
I also suggest a trip to the vet. Medication might be called for.
