Ear infections are a very common occurrence, even in animals. The infections are classified based on the part of the ear that is infected, but it is never a pleasant experience. Loss of balance and hearing problems are a common side effect, but in some circumstances, extreme pain, nausea and even damage to the eardrum can occur. Ears are very sensitive, so it is always important to get them checked as soon as any issues arise.
Denver the dog has been dealing with a bit of an ear infection. The owner stated that this was most likely caused by her playing in the water of a nearby creek. With regular cleaning and medication, Denver should be back to good health. The only problem was her facial expression when it came time for her medication.
