Click to see where most ear-infection medications should go, for puppies.
If the dog's ear gets infected, one of the earlier signs is a funky (putrid or sour, usually) smell from the dog's ears. There may also be residues (often pus-like, brownish, or occasionally bloody) in the ear, and the dog may also scratch his ears frequently, shake his head frequently, or whine and appear un-playful. There are several different types of treatments to use. Some of these come with a long tube, and are intended for injection into the ear canal of the dog, and not merely the external portion of the ear. It is a good idea to ask your vet to demonstrate the usage of the treatment. This step could save you additional visits and anti-microbial ointment costs. Never stick anything into a dog's ear which may damage the sensitive tissue. Do not stick Q-tips (ear canal length varies depending on the size and type of dog; sometimes Q-tips are too long, and additionally, they might become lodged), hard objects, or objects with sharp edges, as these may cause damage. Only use the tip that comes with the medication to treat the area--do not attempt to develop your own. The tips used for ear-infection medications are a specific length, and your vet will prescribe the correct type of medication (and correct tip) for your pet.
