This is why they are breeding grounds for bacteria, yeast, and ear mites.
It is, therefore, very important that you make sure that your dog's ears are kept as clean as possible.
But before you clean it, you need to know how to inspect it.
A healthy outer ear of the dog should look light pink in color, should be clean and should not emit any foul odor.
Look for any excess of dark wax buildup in the ear.
A little bit of dirt and wax is fine.
But if there is excess amount of wax buildup, it could indicate the presence of ear mites.
If your dog has been scratching his ears way too much, then check the inside and the outside of his ear.
Look for nicks, cuts, scabs, infection or mites.
If you think that there is yeast or bacterial infection or ear mites, then take him to the vet as quickly as possible.
However, if you think that there is no infection and no mites, it is time to clean the ears.
Most vets recommend cleaning the visible part of the ear only.
That is, just clean the dirt and wax there.
This can be done using a soft cloth or a cotton ball.
Just dip them in an ear cleaning solution and clean your dog's ears.
Avoid cleaning the ear canal.
You can ask your vet if you should clean deeper into the ear.
There are solutions that the vet may prescribe for this purpose.
These are gently squirted or dropped into the ear canal.
However, most vets suggest that if the dog has had no history of ear problems, then doing this will only lead to problems.
If you do want to clean the canal, then clean it first and then only proceed towards the outer ear.
Make sure to allow your dog's ears to dry out completely.
If your dog breed is one with those long ears, then just pin the ears together over the head for sometime.
This will help in drying the ear canal and preventing any infections.
