Frequent scratching of the ear or shaking of the head
A foul odor coming from the ear
Tenderness or irritability when the ear is touched
Redness or inflammation in the ear
Black, yellow, or cream-colored discharge from the ear Hematoma: swelling of the ear flap from shaking of the head - caused by broken blood vessels - requires care immediately!
Causes
Yeast infections - usually a secondary infection
Bacterial Infections - usually a secondary infection
Ear mites - tiny spider-like creatures, common in puppies & kittens, contagious!
Trapped moisture - from swimming, excess hair, or conformation (floppy ears) - cause secondary yeast / bacterial infections
Whatever the cause, the earlier the infection is detected, the less pain and discomfort your pet will have to endure and the easier the problem will be to resolve.
Prevention
Clean ears regularly with a veterinary ear flushing solution - once every 1-2 weeks unless otherwise directed
Monitor closely for signs and treat early
Treatment
Home Cleaning / Treatment: To clean ears or administer medication prescribed by your veterinarian at home, squirt it directly into the pet's ear. Make sure the medication runs down into the canal. Massage the ear canal between your finger and thumb. Then allow your pet to shake his head to help loosen debris that lies deeper in the canal. Do not use cotton swabs - they may puncture your pet's eardrum. To clean, use small pieces of cotton or tissue to wipe out the ear. Ear Cleaners that we recommend:
Ear Packing - severe or very painful ear infections can be treated by applying specifically formulated medications into the ear at intervals (anywhere from every 5 days to every 3 weeks). We commonly use BNT ear packing, which is a wax based medication with antibiotics, antifungals, and anti-inflammatories in the ears. B.N.T. must be left in the ears for 3 weeks with no other cleaning or treatment, and then your pet must return for flushing.
Flushing under anesthesia - for severe cases
Surgery - in severe cases, or with tumors or foreign bodies
Because there are several different causes of ear infections, there is not one medication that treats them all. Only your veterinarian can diagnose the problem and prescribe appropriate medications. Do not attempt to treat the infection yourself.
