I clean my dog's ears twice each week during regular home grooming. I started using this because the last soap caused drying all over his ears to the point that his skin was peeling off in little white sheets. This is much better.
This is good stuff. My Cocker is prone to ear infections. This helps keep them to a minimal frequency.
Our dog has a chronic ear infection that I've been treating with another excellent product (Vetromax Ointment) that I've only been able to find on this site. I use this ear cleanser every other day to flush his ears and keep them clean. It works great, doesn't have a medicinal-like smell, and costs half as much as at the veterinarian's office! =)
