I have a border collie mutt whose ears stand straight up. Yesterday, I was giving her her routine bath and grooming. I cleaned her ears using a product called "Clean Ears" which I got from Petsmart. Ive cleaned her ears many times before with a puppy solution that I bought directly from my vet, but when I ran out, I just bought some from the store. Anyway, now her ears are sore. THEY ARE NOT INFECTED. She was just at the vet three days ago and had a full physical where he checked her ears, eyes, teeth, ect. She does not have a history of ear infection either. The cleaner is liquid with aloe vera. It says its supposed to be mild and soothing. Sure...Could she be allergic to it, or is this common with a new cleanser? If so, how long should this last and will it happen every time?
