Ear Infections in Dogs: Signs, Causes and Prevention

Important: never put drops, cleaners or home remedies in a sore ear before a licensed vet has checked the eardrum. If the eardrum is torn, some products can cause more damage or permanent hearing loss [1][3].

Ear infections are among the most common ear problems in dogs [1][2]. They usually start with an underlying cause, such as an allergy or trapped moisture. Spotting the signs early, and letting a vet find the cause, makes all the difference.

What is an ear infection in dogs?

• It is inflammation or infection of the outer ear canal, called otitis externa [1][2].
• Something first upsets the normal ear, then bacteria or yeast overgrow and cause the active infection [1].
• Repeated infections can thicken and narrow the canal over time, which makes future problems harder to manage [1][2].

What are the signs?

• Shaking the head, or scratching and rubbing at the ear [1][2][3].
• Redness, swelling or pain in the ear canal [1][2][3].
• A bad smell, or black or yellowish discharge [1][2][3].

A bad smell is one of the typical signs, so it is worth a vet visit rather than waiting.

What causes ear infections in dogs?

• Allergies. Food or environmental allergies are a major cause, and are behind a large share of repeat cases [1][2].
• Moisture. Swimming, bathing or humid weather can leave the canal damp and warm, which helps bacteria and yeast grow [1][2][3].
• Grass seeds. These barbed seeds can lodge in the ear and work their way deeper. They are often too deep for you to see [1][5].
• Other causes include ear mites and other parasites, hormonal conditions, growths in the canal, and too much or the wrong kind of cleaning [1][3].

Which dogs are most at risk?

• Dogs with large, floppy or hairy ears, because less air reaches the canal. Cocker Spaniels, Miniature Poodles and Old English Sheepdogs are examples, but any breed can be affected [2][3].
• Allergy-prone breeds. Vets note that retrievers and terriers carry a higher risk [1]. Labradors belong to the retriever group and have floppy ears too.
• Dogs that swim or are bathed often without careful ear-drying [1][2][3].

Why must a vet check the ear first?

Only a vet can see whether the eardrum is intact and find the real cause, whether that is an allergy, mites, a seed or a growth [1][3]. Shop-bought products are not a substitute for this [1][3].

A torn eardrum can follow a severe infection, an injury or a foreign body. It lets germs reach the middle ear and cause a deeper infection [4]. Most torn eardrums heal over several weeks with proper vet care [4].

That is why this article gives no products or home-treatment steps. Only a vet should decide what, if anything, goes into a painful ear [1][3][4].

How can I prevent ear infections?

• Check the ears regularly for redness, smell, swelling or discharge, especially in floppy-eared or allergy-prone dogs [2][3].
• Dry the ears well after swimming or bathing [1][2][3].
• Treat the root cause. Work with your vet on allergies or hormonal conditions, since repeat infections often point to them [1][2].
• Clean only as your vet advises, with a product and method chosen for your dog. Never push cotton buds into the canal: they can pack debris deeper or injure it [3].
• Check after walks in long grass for seeds on the outer ear and fur [5].
• Ask your vet before trimming or plucking hair around the ear opening [3].

When should I see a vet?

• Any new head shaking, scratching, smell or discharge [1][2][3].
• Sudden head shaking or pawing at an ear after time outdoors, which may mean a grass seed [5].
• Urgently if your dog has a head tilt, loses balance or walks in circles. This can mean the infection has reached the middle or inner ear [3].

Ear care in the Saudi climate

Warmth and moisture help ear infections develop [1][2][3]. In practice, this matters after a swim in the sea or a pool, and in the humid summers of coastal cities such as Jeddah and the Eastern Province. Dry your dog's ears well every time.

There are no Gulf-specific studies on ear infection rates, so this is general seasonal advice. If your dog shakes its head or scratches after time outdoors, in sand, dust or grass, have the ear checked [1][3][5].

FAQ

Why does my dog keep shaking its head?

Head shaking and ear scratching are common signs of an ear problem, from infection to a trapped grass seed. See a vet to find the cause [1][3][5].

Can I use human ear drops or home remedies?

No. If the eardrum is torn, some products can cause lasting harm. A vet must examine the ear before anything goes in [1][3][4].

Can swimming cause ear infections?

Water left in the canal creates a warm, damp space where germs grow. Dry the ears well after every swim or bath [1][2][3].

Are ear infections linked to allergies?

Yes, often. Allergies are a major cause of repeat ear infections in dogs [1][2].

Can an ear infection damage the eardrum?

A severe or untreated infection can tear the eardrum and spread to the middle ear [4]. Early vet care helps prevent this.
