Dog Ear Yeast Infections: Symptoms, Treatment, and Long-Term Management
If your dog is shaking its head, pawing at its ears, or producing a dark brown, waxy discharge with a distinctive sour or musty smell, a yeast ear infection is likely the cause. Malassezia-driven otitis externa is one of the most common reasons dogs visit the veterinarian, and for good reason: untreated ear yeast infections cause significant pain and discomfort, and chronic infections can lead to permanent ear canal changes that make future infections even more likely. The ear canal provides an ideal environment for yeast growth, being warm, dark,... Read more...

Breed Guide Dachshund Ear Infections: What Long-Eared Owners Need to Know By Emiel Maddens  ·  Reviewed in consultation with licensed veterinary professionals  ·  Updated June 2026  ·  15 min read Key Takeaways Dachshunds have long, pendulous ears that completely seal the ear canal, creating the warm, humid conditions that promote yeast and bacterial overgrowth. Despite their relatively small body size, Dachshunds have proportionally narrow ear canals that restrict ventilation and drainage more than many other floppy-eared breeds.

Beagle Ear Infections: Floppy Ears and Outdoor Risks
Breed Guide Beagle Ear Infections: Floppy Ears and Outdoor Risks By Emiel Maddens  ·  Reviewed in consultation with licensed veterinary professionals  ·  Updated June 2026  ·  15 min read Key Takeaways Beagles have long, soft, pendulous ears that seal the ear canal, trapping warmth and moisture to create an environment that promotes yeast and bacterial overgrowth. As a hunting and scent hound breed, Beagles spend significant time outdoors with their ears close to the ground, exposing them to grass, water, debris, and environmental allergens.

Breed Guide Poodle Ear Infections: Ear Hair, Water, and Prevention By Emiel Maddens  ·  Reviewed in consultation with licensed veterinary professionals  ·  Updated June 2026  ·  15 min read Key Takeaways All Poodle sizes (Standard, Miniature, and Toy) grow dense, curly hair inside their ear canals that traps moisture, debris, and wax while blocking airflow. Poodles were originally bred as water retrievers, and their continued affinity for water means frequent moisture exposure to already-compromised ear canals. The ear hair plucking debate is particularly relevant for Poodles, with veterinary opinion divided... Read more...

Breed Guide Shih Tzu Ear Infections: Hairy Canals and Chronic Issues By Emiel Maddens  ·  Reviewed in consultation with licensed veterinary professionals  ·  Updated June 2026  ·  15 min read Key Takeaways Shih Tzus grow extremely dense hair inside their ear canals, which traps moisture, debris, and wax while severely restricting airflow to the ear canal lining. Their brachycephalic (flat-faced) skull structure contributes to narrower ear canals and altered drainage patterns that compound the hair obstruction problem. Shih Tzus have floppy, heavily coated ears that further reduce ventilation, creating a... Read more...
