How to Soothe Your Dog's Itchy Ears

Know when to take your dog to the vet. If your dog is constantly scratching its ears, it’s important to visit a veterinarian for a thorough examination. The vet may use an otoscope to inspect the ear canal and check for any damage to the eardrum. They can also identify other potential causes of ear irritation. For instance, the vet may take a swab to diagnose an infection.

• If your dog appears to be in pain or makes the examination difficult, the vet may administer a sedative and clean the ears. This allows for a better view of the eardrum and ensures topical medications are absorbed effectively.
• Avoid applying any medications without consulting your vet. If the eardrum is damaged, certain medications can reach the middle or inner ear, potentially causing permanent balance issues or hearing loss (including deafness).

Exercise caution when using tea tree oil. Tea tree oil is often recommended for skin inflammation and infections, but it contains terpenes that are toxic to dogs. Animals can only tolerate tea tree oil diluted to a concentration of 0.1-1%. However, most shampoos, antiseptics, and skin treatments available at pet stores contain higher concentrations, which can be dangerous for dogs. If using tea tree oil products, ensure the oil is properly diluted.

• Watch for signs of terpene toxicity after applying tea tree oil to your dog. Symptoms of toxicity include nausea, vomiting, and paralysis (common in both dogs and cats). Severe cases can lead to paralysis, seizures, or even death.

Consider using antihistamines for your dog. If the cause of your dog's ear itch is unclear, you can provide temporary relief while determining the root cause. Common antihistamines like Diphenhydramine can be administered at 2 mg doses, typically in tablet form, three times daily. Antihistamines work by blocking and preventing inflammation.

• Note that even after starting treatment, your dog may continue scratching. Additionally, antihistamines may not resolve all cases of ear itchiness. While some dogs experience relief, only about 10-15% show significant improvement.

Provide temporary itch relief for your dog. Veterinarians may prescribe short-term corticosteroids to alleviate itching while identifying a targeted treatment. Corticosteroids are potent anti-inflammatory drugs that effectively reduce itching. You can also consult your vet about over-the-counter creams containing 0.5-1% hydrocortisone. Applying these creams around the outer ear can soothe skin inflammation.

• Be cautious, as steroids should not be combined with certain medications like NSAIDs (non-steroidal anti-inflammatory drugs) used for arthritis. Combining these can cause severe stomach ulcers, leading to bleeding and potentially fatal outcomes.

Look for symptoms of ear infections. Ear infections often cause significant pain and discomfort, so watch for persistent scratching or rubbing of the ears. You may also notice redness, swelling, warmth, foul odor, or discharge (such as thick wax or pus). Ear infections can result from various causes (ear mites, bacteria, or fungi), so a veterinary diagnosis is essential.

• If unsure whether your dog has an ear infection, compare both ears. If one ear shows signs of irritation or abnormality, an infection is likely.

Take your dog to the vet. There are numerous causes of ear infections, so a veterinarian should diagnose and prescribe antibiotic ear drops. If your dog has had ear infections before, the vet may take a swab for a culture to identify the bacteria causing the infection and determine the appropriate antibiotic. Severe ear infections may require a combination of ear drops and oral antibiotics.

• Many treatment options are available. Your vet will choose the best one for your dog and provide instructions on dosage and duration. The treatment plan depends on your dog's size and condition.

Clean your dog's ears. Choose a gentle, pH-balanced ear cleaner that moisturizes and evaporates easily. Opt for a liquid solution rather than wipes, as it can penetrate deeper into the ear canal to remove debris and bacteria. Insert the bottle tip into the ear canal and gently squeeze to release the solution. Cover the ear with a cotton ball and massage the base of the ear. Remove the cotton ball and wipe away any excess fluid. Repeat until the ear is clean.

• If your dog tilts its head, the eardrum may be ruptured, and the cleaner could reach the middle or inner ear. Stop cleaning and consult your vet immediately.
• Cleaning ear debris can reduce bacteria and alleviate itching. However, if cleaning causes pain or swelling, stop and seek veterinary care.

Identify allergy triggers. In some dogs, recurrent and unexplained ear infections may be linked to allergic reactions. Dogs can be allergic to environmental factors (like dust or mites) or specific food ingredients. Discuss this possibility with your vet if ear infections persist—they may recommend an elimination diet to see if symptoms improve.

Look for signs of external parasite infections. If both ears appear healthy but your dog continues to scratch, it may have an external parasite infection (such as fleas or mange mites). Check for fleas or flea dirt (flea feces) that may have migrated from the fur into the ears, causing irritation.

• Fleas move quickly, so they may not always be visible. Flea dirt looks like brown specks and, when wiped with a damp cotton ball, leaves an orange stain from dried blood.
• Mange mites are microscopic and invisible to the naked eye. However, you may notice duller fur, especially around the ears and legs.

Follow your vet's treatment plan. If you suspect your dog's ear itch is caused by fleas or mange mites, consult your veterinarian about anti-parasitic products to treat the infection and relieve itching.

• Many topical treatments are available to effectively eliminate fleas and mites. Your vet can recommend the best product and determine the appropriate dosage for your dog.

Look for signs of internal parasites (ear mites). It's difficult to see deep inside your dog's ear, so you may only notice an internal infection if your dog scratches excessively or if you see thick, crumbly brown earwax. Ear mites are a common cause of earwax buildup and infections in dogs. A vet will need magnification tools (like an Auroscope or otoscope) to spot mites moving around or to identify mites or their eggs under a microscope.

• Otodectic mange or ear mite infestations can cause mites to feed on earwax, leading to infections throughout the ear canal.

Follow your vet's ear mite treatment plan. Your vet may recommend over-the-counter treatments containing Pyrethrin. Typically, you'll apply Pyrethroid-based medication into the ear canal once or twice daily for 10-14 days. Topical Pyrethrin is generally safe for dogs as it is poorly absorbed into the bloodstream.

• In theory, dogs risk poisoning if they ingest Pyrethrin or lick it off another treated dog. Symptoms of poisoning include drooling, muscle tremors, agitation, and, in severe cases, seizures. If you notice these signs, keep your dog in a dark, quiet room to reduce agitation and contact your vet for advice.

Watch for head tilting and excessive scratching. Foreign objects like grass or foxtails in the ear canal are common issues for dogs. Be alert if your dog suddenly starts scratching after a walk or tilts its head to one side while frantically scratching its ear.

• Objects like grass can migrate deeper into the ear canal, causing intense itching. A head tilt may indicate a foreign object lodged inside the ear.

Take your dog to the vet to remove foreign objects. You cannot see deep into your dog's ear to locate foreign objects. Due to the ear canal's "L" shape, objects can become lodged deep inside. A veterinarian will use an otoscope (a magnifying and illuminating tool) to inspect the ear thoroughly. They can remove the irritant using a specialized long tool called biopsy forceps.

• Removing foreign objects is usually quick and painless for your dog.
