Otitis can be an extremely painful condition for dogs, however scientific evidence now supports a safe and easy solution.


Predisposing factors

  • Unfavourable microenvironment impeding normal protective mechanisms
  • Certain ear conformations such as: stenosis, dense hair growth in the earcanal, excessive cerumen production (Cocker Spaniel, Shar Pei, etc.)

Primary causes

  • Capable of causing otitis externa alone (foreign bodies, parasites, tumours.)
  • Allergic dermatitis (atopic dermatitis, adverse food reactions.)
  • Parasites (Otodectes, Demodex, Sarcoptes.)
  • Miscellaneous (hypothyroidism, ear canal neoplasia, pemphigus foliaceus.)

Perpetuating factors

  • Bacterial & yeast secondary infections
  • Otitis media, ear canal stenosis.

Otitis externa in dogs (erythemato ceruminous)

= 75% are allergic dermatitis related2


Effective treatment of otitis externa requires the persistence of antimicrobial actives in the ear for a period of time. Sometimes veterinarians are reluctant to cleanse ears whilst treating for otitis externa in case cleaning will diminish the action of treatment medication(s).

A recent study1 has confirmed that the prolonged concentrations in the ear canal of the gentamicin and miconazole actives in EasOtic® at 10 and 15 days following treatment is not affected by the cleaning of ears with EpiOtic® 30 minutes prior to treatment.


  • Gentamicin concentrations were above the MIC90 of Staphylococcus pseudintermedius strains (0.5 μg/mL) on D10 and D15.
  • Average miconazole concentrations were above the MIC90 of Malassezia pachydermatis strains (0.75 μg/mL) on D10 and D15.

No side effects were reported in the trial.
