I don't know about other people but I have had ongoing ear infections with Dodger ever since I got her and she had them even before that according to breeder I got her from. She gets her ears cleaned and hair pulled weekly. She does swim a lot when it's warm but I have a solution made up of water/vinegar and some alcohol and I spray it around the outside of the ear canal before and after swimming.
With Vega..never one infection, not once, not even slight irritation. His ears are always perfect but poor Dodger..
She also has allergies but I don't know if that would have anything to do with it. I've tried several things. I have Zymox on hand for if it gets really bad and that's what im using currently I also have some antibiotics the vet gave me last time she had an infection but what do you guys do to prevent them?
I feel awful working in grooming for as long as I have and having a dog get ear infections.. i'm not sure what to do differently.
