Query: Irritated my dog's ears

I have an Old English Sheepdog, Jasper, who is prone to ear infections and is allergic to California native grasses (yes, a dog allergic to grass!). We first used this product per a vet recommendation and it ended up irritating her ears (making them more red and itchy). So, the vet suggested Virbac Epi-Otic and that seems to make Jasper much happier. Some other reviewers suggest soaking a cotton ball and squeezing the solution out into the ear canal as more tolerable for the dog than squeezing it into her ear canal--I'm going to try that out because Jasper definitely doesn't like having the bottle squeezed anywhere near her ear. My vet also recommended that you don't have to worry about putting a decent quantity into the ear canal and then you should massage the ear to give the solution a chance to break up the debris in the ear before you let the dog shake it out or if you wipe out the ear canal with a paper towel (big dogs).
