Well... probably not, unfortunately!
Let me explain...
Ear infections (otitis externa) are quite common, and floppy eared dogs are most often affected.
Otitis externa is commonly caused by yeast, bacteria or a combination of both. Quite often, the ear drops that I prescribe have a combination of anti-fungals to treat the yeast, anti-biotics to treat the bacteria and anti-inflammatories to decrease the pain and inflammation. The names of a couple of ear medications (drops) I commonly prescribe are Surolan and Otomax.
Oral antibiotics are rarely needed to treat ear infections, as the drug doesn't get to the site of the infection effectively. When you give an oral antibiotic, it ends up in the blood stream, and this is not helpful for treating ear infections which are on the skin surface within the ear. Occasionally I use oral antibiotics if there are signs of an INNER ear infection. This is rare. In 14 years of practice, I have given oral antibiotics for ear infections on less than a dozen occasions, and have treated several thousand ear infections.
In terms of what you can do at home without seeing a vet, I could make a few suggestions:
1. Burrow's Solution (Buro-sol, http://www.feelbest.com/Pages/ItemDetails.aspx?GroupID=EADRO&TYPE=FINE&LINKPAGE=ItemDetails.aspx&ID=05546000017
). In Canada, you can get Burrow's Solution over the counter at a pharmacy. I believe it is widely available in the USA as well. It is a gentle astringent that is very useful in treating ear infections. Many veterinarians carry it, compounded with 2% hydrocortisone (for that you would need a prescription). But you could certainly try it twice daily for 7 days in your dog. Instill 3-5 drops into both ears twice daily for a week.
2. You could start your dog on Essential Fatty Acids, orally. These decrease inflammation in the body and are very helpful with skin, hair and ear issues. EFA-Z and DermCaps are a couple of brands. It takes 8 weeks to see improvement.

Most ear infections need prescription drops to improve. This means a visit to your vet, I am afraid.
Good luck with your dog. If this has been helpful, please hit the green "Accept" button. I will still be here to provide more information if you need it!
