My dog has developed a cyst today. I don’t see any bite marks, no oozing, no fever, she’s playful and acting normal. What could be the cause?

It could be Sally has a sebaceous cyst, which is a plugged oil gland in the skin. These can be common. Do not try to pop it, which will introduce infection into the area. Make an appointment with her vet, who can drain it and remove the cyst sac if needed. Best of luck, I hope this helps!
