As pets (especially canines) have been domesticated and crossbred, their ears have gotten longer and droopier - a far departure from the ancestor wolf. As a result, the external ear area of pets requires extra care to prevent or minimize ear infections, wax buildup, etc. Natural Ear Care's formula uses a safe and effective combination of natural ingredients. Apple cider vinegar is a natural nontoxic folk household cleaner that has traditionally been used for deodorizing, disinfecting and to control the growth of unfriendly bacteria and other microorganisms. Deionized water has been treated to remove all minerals and inorganic chemicals. Hydrogen peroxide is generally found to be helpful in softening and removing earwax. Magnesium and zinc sulfate are used in folk remedies for their tonic and astringent capabilities. Natural Ear Care comes in a 1/2oz (15mL) bottle, which is much smaller than the 4oz ear washes typically found in stores. This formula is much more concentrated and effective. Besides, if you've ever had water violently squirted in your ear, you'd know why we don't feel it's necessary to do that to our beloved pets. Ear wax provides a perfect medium for the establishment and growth of several microorganisms leading to discomfort, odor and different grades of ear infection. Natural Ear Care is a dependable and effective way to maintain ear hygiene for your pets.
