studies showing that about 20% of dogs experience ear disease at some point.
When bacteria are the culprit, antibiotics
for dog ear infection become essential for treatment. This guide
covers the most effective dog ear infection medicine options,
how they work, and important considerations for pet owners.

ear canals are structured differently than humans' - they're L-shaped and can
easily trap moisture, creating the perfect environment for bacterial growth.
The most common bacterial causes of canine ear infections include:
- Staphylococcus pseudintermedius
- Pseudomonas aeruginosa
- Proteus mirabilis
These
infections often cause:
- Red, inflamed ear canals
- Yellow or brown discharge
- Foul odor
- Pain and head shaking

first line of defense is usually medicated ear drops containing:
- Enrofloxacin (Baytril Otic): Particularly effective
against Pseudomonas

antibiotics
These dog
ear infection medicines typically require application 1-2 times daily
for 7-14 days.
2. Oral Antibiotics
For
severe or recurrent infections, vets may prescribe:
- Cephalexin: First-choice oral antibiotic

infections
