Questionwhy do turtles blow bubbles?
AnswerJennifer,
Turtles aren't supposed to blow bubbles.
Any sign of bubbles mean your turtle has a respiratory infection and needs to see a vet ASAP. Usually turtle get infections like this when they aren't being given enough heat or are being kept in a dirty cage.
Please take your turtle to a vet soon. If there is no vet in your area, go to a dog or cat vet, that is fine.
While you are at the vet, you can talk to the vet about what to do to prevent this in the future. I can't help you much since you didn't include much information. Feel free to write me with any more questions.
