Ear Infection Remedies for Pets

My cousin's lab puppy's ear was red and hot. there was dried blood and dirt in it too. i have a book of home remedies for dogs and cats. cleaned ear with acv plus water then mixed 1 tbsp pure aloe vera gel and 1/2 tsp hydrogen peroxide. she's getting over it nicely' at first i used 2 eyedroppersful but got better results with 3 she had a small growth under an eye on the same side as the affected ear and it has disappeared. could it have been a mite? just want to mention,i mixed up the mixture to put in her ear fresh everyday.

My shih tzu dog had a rash in one ear, I treated it with tea tree oil, I put it on with a cottonbal, it cleared up in two days.
