Zinc Oxide Ointment
Our Dog's left ear started having tarry stuff which smelled like yeast, so I came across here as always the first thing comes to my mind after facing a medical problem is visiting earth clinic and searched for a cure, things I tried with no avail :
-) Mixture of garlic and olive oil, boiled, let cool, and dripped in ear ( not even helped, but caused the formation of a gray stuff in his ear which we believe it was pus )
-) Apple cider vinegar, helped a bit at first but couldn't successfully cure anything, We insist which caused dryness in his ear and after scratching the ear by the dog it caused injury so we stopped using it.
The infection developed to the another ear, and what helped at last was :
+) Zinc oxide ointment ( mixed with a little bit of another antibiotic ointment, we used mupirocin but I think another ones work as well )
* How we applied the ointment *
I just put some mixture of ointments on calf of my hand, and with my finger tip ( don't forget to wash your hand and cut your nails or you might scratch the wall of the outer ear and cause injury ) of another hand apply the ointment to all areas of outer ear ( the inside of ear not outside of it, it's just called outer ear or external ear but in fact it is the inside of the part of ear which is like a plate ), don't be afraid of large dose using of ointment as it won't harm and will be absorbed by skin and helps immune system to fight infection but don't use too much to block the hearing and make the area prone to absorb new infections from environment, after covering the whole outer ear, try to GENTLY put your finger in ear canal whilst your finger tip has ointment on it and apply the ointment on the entry and very beginning of ear canal and try to turn your finger so very GENTLY ( caution : you don't need to go too deep )
Just after one day, clean the ear with your finger tip by help of a soft tissue and re apply the ointment, as you go through you'll notice the stuff is becoming lesser and lesser and will disappear just after few days .
Our dog got recovered in his both ears just after few days, with no side effects, despite the fact that there were some injuries in his ears by using inappropriate substances and scratching his ears by himself .
Beside the therapeutic effect of this remedy by chronically helping immune system in helping infections, as some infections cause dryness in ear, the ointment can soften the inside of ear and alleviate the feeling of discomfort for the pet. I hope it helps.
There is an enzyme based product called Zymox which works wonders on ear infections. I had a 16 yo dog whose ears were red and inflamed, and after ordering this product (zymox otic hc 1%) it cleared up within a day. Recently I gave a bottle to a friend whose dog has chronic ear infections, and the drugs and cleanings did nothing. She was constantly shaking her head, poor thing was in agony. Within 5 days all shaking stopped. You can order from amazon. Be sure to read the directions, and don't clean the ear first, just apply to dirty ear.
