What is an ear mite?
Ear mites, scientific name Otodectes cynotis, are microscopic, spider-like parasites that live in the ear canals of dogs and cats. They feed on earwax, skin oils, and tissue debris. Though barely visible to the eye, they can cause intense irritation and inflammation in the ears of their host.
What causes ear mites in dogs?
Despite their size, ear mites are masters of transmission. Responsible owners must recognise what causes ear mites in dogs to ensure ongoing protection for their furry friend.
Direct contact
The most common way that ear mites are transmitted is by close physical contact with an infected animal (another dog or cat). Even a brief interaction can be enough for mites to move from one host to another.
Contaminated environment
Mites can survive short periods away from a host in warm, moist areas like kennels, doggy daycare, or grooming stations. Dogs that frequent these environments may pick up mites without ever touching another animal.
Breeding environment
Young puppies may get ear mites from their mothers, particularly in breeding or shelter settings where close quarters and shared spaces are common.
Why are ear mites a problem?
Ear mites in dogs are more than an annoyance. If left untreated, they can lead to a range of health issues:
• Itching and discomfort: Dogs with mites may scratch until they cause wounds or hair loss around the ears. Another sign may be head shaking or rubbing of the ears on the ground.
• Ear infections: Mites trigger inflammation and increase the risk of secondary bacterial or fungal infections.
• Spread to other pets: Ear mites are highly contagious, making early diagnosis essential in multi-pet households.
How to prevent ear mites in dogs?
Preventing ear mites is about protection and awareness. Using a vet-recommended parasite control product such as NexGard or NexGard SPECTRA® for Dogs will treat and control ear mites.
To lower the risk:
- Avoid exposing your dog to unwell or untreated pets
- Wash bedding and toys regularly
- Maintain regular vet check-ups, especially if your dog has sensitive ears or recurring infections
