My dog has an inflatable bump in his ear, could it be a tumor?
An inflated bag in a dog's ear
An inflated bag in a dog's ear may be a tumor or a mass. The owner can gently touch the inflatable bag with his hand to see if it is hard or soft. Check to see if there is fluidity in the bag and if the dog is in pain. If it is difficult to judge, it is best to take your dog to a pet hospital for examination and let a professional doctor diagnose and treat it.
