Rule out the underlying cause

Very often, an ear infection means that there is some underlying cause that is causing health problems in your dog. Only after treating this underlying health problem can you prevent ear infections in your dog.

Sometimes these underlying causes can be allergies, tumors, hormonal imbalance, etc. But, most often, skin allergies are responsible for ear infections in dogs. These skin allergies can cause inflammation, and the ear canal also breeds yeast and small bacteria that can further worsen the situation.

Keep your dog’s ears dry

Many yeast and bacterias live in warm places, and dogs’ ears are a perfect place for these bacteria to stay and grow.

The best prevention measure for dogs that are more prone to these bacterial ear infections is to clean their ears once every 5 to 10 days. After exposure to water, immediately clean your dog’s ears.

Before your dog takes a bath or goes swimming, add a cotton ball to your ear and clean the inside flap with a towel after the dog takes a bath.

The main reason for the ear infection is moisture, so whenever the dog comes home after bathing or swimming, make sure to dry your dog’s ears properly. Also, dogs are prone to chronic diseases, so try to find the underlying reason for these recurring chronic diseases. It can be allergies or something else.

You can also clean your dog’s ears at home, but you must be very careful during the whole process of cleaning. You can use the vet-suggested solutions to clean the ears of your dog. Soak the cotton ball with the solution and then add the solution into the dog’s ear canal, being very careful.

 After this, gently massage your dog’s ear and remove any debris with the help of a dry cotton ball, but you have to be careful while doing so.

Don’t insert the cotton inside the ear canal as it may push the wax deeper into your dog’s ear canals, causing trouble for your dog.

Consider giving supplements to your dog

There is no alternative to a good nutrition-filled diet, but still, you can give your dog some supplements to prevent ear infections in dogs.

Before you give your dog any supplement, consider going to the vet and checking the supplements again. If the root cause of ear infections in your dog is allergies, then you can give omega-3 supplements to your dog.

A malfunctioning immune system can cause further trouble by the deterioration of your dog’s health and can make your dog more prone to infections. Giving a probiotic supplement can help you to make your dog’s immune system strong.

Reconsider before plucking your dog’s hairs

Plucking dog hairs can be beneficial, but it is not always beneficial. For example, if the dog has healthy ears and has no ear infections, then the advice is not to touch the dog’s hair. But if the dog has a very hairy ear canal, then plucking the hair frequently after a short time can reduce the risk of your dog getting an ear infection.

The best advice is to consider a groomer for hair plucking in the case of dogs, as if the pet owners perform this procedure at home, it will be very risky.

 Also, if you notice any change in your dog’s behavior, the main advice is to contact the vet if any such situation occurs.
