Ear infections in dogs

What do ear infections in dogs look like?

If you notice your dog acting unusually – exhibiting ear sensitivity or head shaking ­– they may have an ear infection or ear inflammation, (also known as canine otitis externa). 

This inflammation, which affects the ear canal, can be painful for dogs and in most cases will not improve without medical treatment. Plus, dogs that have had it once may be prone to having recurring ear infections. 

Untreated or recurring ear infections can lead to permanent changes in the ear canal.

Ear infection symptoms can include:

  • Itching and scratching ear
