Dogs are born deaf or can become deaf over time or due to an injury.

Is your dog not responding (or stopped responding) to normal sounds at normal volumes? They may be facing hearing loss (even though some “deaf” dogs can still hear very low or very high-pitched sounds). How do you know if your dog may have a hearing problem? See the symptoms below.

Canine Deafness: Symptoms

If you see any of these symptoms with your dog, see your vet immediately to rule out hearing problems!

  • Changes/inattentiveness with obedience
  • Repetitive head shaking or tilting to one side
  • Confusion or unable to follow familiar vocal commands
  • Difficulty waking up
  • Painful or smelly ears
  • Problems with balance

Learn about the common causes behind K9 deafness below.

Canine Deafness: Causes

  1. Genetic or Congenital Deafness

Irreversible congenital deafness stems from two genes, the piebald or merle gene. According to the Pet Health Network, 90 different canine breeds carry the gene for congenital deafness.

  • word image 1003 3 canine deafness Dogs with the “piebald gene” have a white coat (but not all white dogs are deaf). They are often deaf due to the absence of cells called melanocytes (responsible for pigment or color). Also, without this stem cell source, their body is not able to make the special layer of cells in the inner ear required for the dog to hear. These dogs often have “blue” eyes (not a true eye color, it comes from a lack of color-producing pigment in the affected dog’s iris).
  • Congenital deafness is also linked to the “merle gene.” This gene creates a merle – or dappled – coat and often blue eyes.
  1. Infections, Inflammation & Injuries word image 1003 4 canine deafness
  • Long-term allergies, infections and inflammation of the ear canal may also lead to hearing loss. Always work with your veterinarian to quickly treat any hearing issues before they become irreversible.
  • Keep ears free of dirt, wax, ear mites, allergens and other foreign bodies that could lead to hearing loss (conductive deafness) or permanent hearing loss.
  • Very loud noises can also cause temporary or permanent K9 hearing loss.
  • Blunt trauma to a dog’s head may cause temporary or permanent hearing loss from blood in the inner ear.
  • Also, some drugs (including some treating ear infections or inflammation) may cause ototoxicity (drug or chemical damage in the inner ear) leading to deafness.

Hearing loss due to the aging process can happen gradually but also suddenly. Older dogs may be challenged by a form of “acquired hearing loss” called presbycusis. This irreversible form of hearing loss affects the receptors in the cochlea and deteriorates their ability to transmit sound to the senior dog’s brain.

Is Your Dog Deaf?

Deafness in dogs can be diagnosed with a BAER test on dogs older than 6 weeks. (The same test is used to check the hearing of human infants.)

13-year old Bella is not letting her deafness slow her down!

The Brainstem Auditory Evoked Response test painlessly measures electrical activity within the brain in response to sound stimulation. If a dog is deaf, the BAER response is flat or reduced in scale. The test usually lasts 10-15 minutes and tests each ear individually and determine if a dog is deaf in one ear (unilateral deafness) or both ears (bilateral deafness).
