Advices from our vets
The shape of your dog’s ear canal is very different from that of a human. Because of that, dirt and cerumen cannot exit the ear duct as easily, which is why it is important to regularly clean your companion’s ears! The accumulation of cerumen in the ear duct facilitates the multiplication of bacteria and yeast, and this can lead to an otitis (inflammation/ infection of the ear).
This is even truer for dogs with droopy ears because the canal is less ventilated. These dogs are more prone to otitis.
Finally, it allows you to check that everything is alright, especially when your dogs is scratching its ears!
