What Is an Otoscope? Definition, Types, and How It's Used for Pets
Created on 07.02
Have you ever caught your dog scratching at their ears or shaking their head like they're trying to get something out? We can often tell when something's not right, even if our pets can't tell us directly. One of the most common causes of this behavior is an ear infection.
Ear infections, also called otitis externa, are the most common ear disease in dogs. They affect up to
20% of dogs during their lifetime. These infections can cause swelling, redness, pain, buildup of debris, and a strong odor. If not treated, they can lead to long-term pain or even hearing loss.
That's where a helpful tool comes in: the otoscope. Whether you're a vet or a concerned pet parent, an otoscope helps you see inside your pet's ear canal, catch problems early, and make informed care decisions. In this article, we'll explain what an otoscope is, the different types, and how it helps you keep your pet healthy and happy.
What Is an Otoscope?
An otoscope is a handheld medical device used to look inside the ears. Imagine a flashlight with a magnifying lens, made to give you a better view of the ear canal and eardrum. Vets use it to check for infections, wax, or foreign objects in pets' ears. Some newer models are made for home use too.
Otoscope technology
goes back to the 1800s, when doctors used lights and mirrors to look into the ear. Today's otoscopes include fiber-optic lights and digital features that make it easier to get a clear view.
Why Otoscopes Are Essential for Pet Owners and Veterinarians
Ear problems in pets are common. Dogs and cats with floppy ears or lots of hair around the ears are at higher risk. Common issues include:
- Bacterial or yeast infections
- Ear mites (especially in kittens or wild animals)
- Foreign objects like dirt or grass
- Too much wax or moisture
Without regular checks, these issues often go unnoticed until your pet is in pain. That's where an otoscope helps.
Early Detection, Less Discomfort
An otoscope helps you or your vet see inside the ear canal. This lets you spot signs like redness, swelling, debris, or mites early. Early treatment means less pain and a faster recovery for your pet.
At the Clinic vs. At Home
Vets use otoscopes every day during checkups. But with the rise of digital and pet-specific models, more pet owners now use otoscopes at home.
Let's say your dog, Max, has been scratching his ear. Instead of waiting for a vet visit, you use your Reescope otoscope. You see some wax and redness. You send a video to your vet, who confirms it's likely a mild infection and suggests treatment—no clinic trip needed.
Different Types of Otoscopes
Whether you're a vet or a caring pet parent, not all otoscopes are the same. Each type is made for different needs—from quick home checks to full examinations at the clinic. Here's a look at the four main types of otoscopes and what they offer.
1. Standard Otoscope
This is the most common type found in veterinary clinics and hospitals. It's a handheld device with a light and a magnifying lens that helps to see inside the ear canal.
Best for: Basic ear examsPros: Affordable, reliable, and durableCons: Limited view
These otoscopes are great for simple checks but may not be the best choice for detailed diagnosis or home use.
2. Video Otoscope
A video otoscope has a built-in digital camera and screen. It gives a clear and live view of the ear canal. Many models include zoom and adjustable lighting for better accuracy.
Ideal for: Vets and pet owners who need better imagesAdvantages: High-definition visuals, zoom, image and video captureDisadvantages: More expensive, may take some practice to use
If you want a professional option, the
Penguin Plus-V ENT Otoscope offers clear visuals and is easy to use in clinics or at home.
3. Pet Otoscope
These otoscopes are designed with pets in mind. They come with flexible tips, small speculums, and easy-to-hold grips to make ear checks more comfortable for pets.
Best for: Pet owners and vets who often examine animalsPros: Comfortable, pet-friendly, often wirelessCons: A bit more expensive than basic models
At Reescope, we create otoscopes made for even the most wiggly pets. The
Multi Functional Endoscope is one of our top options. It's flexible and useful for more than just ear checks.
4. Wireless/USB Otoscope
These otoscopes connect to your smartphone, tablet, or computer. They let you view live images on your screen, making it easier to spot issues.
Best for: At-home checks, tele-vet appointmentsPros: Lightweight, portable, captures images, affordableCons: Needs a steady hand and basic tech skills
Remember: These are great tools for monitoring, but always ask your vet if you're not sure what you're seeing. For a user-friendly choice, explore our

When and How to Use an Otoscope at Home
Using an otoscope at home might feel intimidating at first. But with the right tool and a gentle touch, it can be a safe and simple way to check your pet's ear health. Whether you're tracking an ongoing issue or just doing a routine check, learning to use an otoscope can help you spot problems early. This can reduce stress and prevent serious issues later.
Important: If your pet is in pain, bleeding, or shows signs of a serious infection, contact your vet before using an otoscope.
Step-by-Step Guide to Using an Otoscope at Home
Step 1: Choose the Right Otoscope
Pick a device made for pets. Look for one with soft, flexible tips and a lightweight design. Wireless or USB models, like the
USB Flexible Endoscope, are great for home use. They let you view the inside of the ear on your smartphone or tablet.
Step 2: Prepare Your Pet
Pick a calm time, such as after a walk or meal. Gently hold or cuddle your pet in a quiet space. If your pet moves a lot, ask someone to help keep them still.
Tip: Give a treat before and after the exam to make the experience more pleasant.
Step 3: Examine the Outer Ear First
Before inserting anything, inspect the outer ear. Look for:
- Redness or swelling
- Bad smells
- Wax buildup or discharge
- Head shaking or frequent scratching
If you notice anything unusual, stop and call your vet.
Step 4: Turn on the Otoscope
Turn on the light or connect the device if it uses your phone or tablet. Make sure the speculum (the cone-shaped tip) is clean and properly attached.
Step 5: Carefully Insert the Speculum
Lift the ear flap. Slowly insert the tip into the ear canal, just enough to see inside. Never push or force it. The ear canal is L-shaped, so angle the tip slightly downward and then inward.
Move slowly and gently. Watch your pet's body language. If they seem uncomfortable, stop and take a break.
Step 6: Observe and Record
Look for anything out of the ordinary, such as:
- Redness or swelling
- Extra wax or fluid
- Black debris (possible ear mites)
- Cuts, sores, or foreign objects
If your otoscope has a camera, take a photo or video. This can help track changes or assist your vet.
Step 7: Clean the Otoscope
When you're done, remove the tip and clean it. Use alcohol wipes or wash it with soap and water. Let it dry before storing it away.
With practice, using an otoscope at home can become part of your regular pet care routine. Just remember to contact your vet if anything looks serious or doesn't improve.
What to Do — And When to Call the Vet
Using an otoscope makes it easier to check your pet's ears. But it's not a replacement for a vet visit. If you see anything strange—especially if it gets worse or doesn't improve—call your vet.
Some signs to look out for include:
- Swelling
- A bad smell
- Black discharge
These can be signs of an infection, mites, or something more serious.
