Warm ears on a dog is usually normal, however, if it has a foul odor and is irritated or swelling, it may be an ear infection. Applying some peroxide using cotton buds on the outer ear will kill certain germs but is only a temporary solution. Your best bet is consulting your vet immediately. Your pet may need antifungal medicine or antibiotics and your vet is the best person to ask regarding this.

It depends on what type of dog it is.
Some poodles can develop chronic yeast infections in their ears. This is often ascribed to excessive moisture and hair in the external ear canal that promotes a warm, humid environment that yeast thrive in. This can be managed through routine ear cleaning with a mild dog-appropriate ear cleaning solution.
I worked as a veterinary assistant for years and can only recommend that you bring your dog in to see a veterinarian. Home remedies either don't work, or cause even more damage. An untreated ear infection could progress further into the ear, causing more pain and possibly requiring corrective surgery. Ear infections can be easily treated by medicine prescribed by your vet.
