This often depends on your dog. Droopy-eared breeds such as Cocker Spaniels and Basset Hounds will require more regular ear cleaning as the can be more prone to ear infections. This is because longer droopy ears allow less air flow, and debris and moisture may easily become trapped in the ear canal, which can result in a yeast infection.

Dogs that like to swim will also require regular ear cleaning as the extra moisture can predispose them to ear infections. Additionally, you should always be on the lookout for ear mites on your dog as they are also a potential cause of ear infections and can also be transmitted to other pets.

In short, it’s important to clean your dog’s ears regularly enough to avoid infections, but not too often as this can damage the canal or cause irritation that can result in further problems. If you’re unsure, it’s best to ask your vet as they’ll be able to recommend a cleaning schedule that suits your dog’s unique needs.
