Last year, I rescued a Cocker Spaniel. By "rescue" I mean I found her wandering in the road, with no tags, covered in dirt and knotted fur. I've never owned a Cocker, and was unprepared for all of the grooming needs. Her ears fill with wax daily, and if not cleaned, will get very stinky. This product does a great job of cleaning the wax and leaving a fresh scent. The solution does not bother her at all. I can use it on a cotton swab, or just squirt it into her ear, massage ears, and let her shake it out. It's colorless, and does not damage anything in the house when she shakes it out. I haven't tried that homemade ear cleaner that dog owners "in the know" use, because that one can stain stuff in the house.
