Circling in Hamsters

Hamsters are very active so it’s normal to see them running around their cages and on their exercise wheels. But if your hamster suddenly begins circling and tilting its head to one side while it is running around then this indicates something more concerning. Veterinary care may be necessary if your hamster is circling, so being able to recognize this issue is important for your hamster’s health.

Causes of Circling in Hamsters

Circling in hamsters occurs when a hamster has a head tilt. Head tilts are usually a result of an inner ear infection due to bacteria but other causes may be present.


With an inner ear infection, bacteria from a dirty environment or a respiratory infection enters the ear canal. The pressure that the infection causes inside the ear canal may result in a hamster feeling off-balance and in pain. This results in circling when it walks and some hamsters may even fall over.

Neurological problems due to trauma or a brain disease like epilepsy can also cause circling in hamsters. These issues are not as common as a bacterial infection in the ear but are still possible reasons for this type of behavior.

Diagnosing the Cause for Circling in Hamsters

While circling in hamsters may be an obvious behavior to observe, in order to know for sure what is causing this some tests may need to be run.

Since an ear infection is the most likely reason for the circling, debris from inside your hamster's ear may be looked at under a microscope. This will check to see if bacteria from an infection is present and, if it is, an ear infection will be diagnosed.

Neurological problems are harder to diagnose. If your hamster was recently injured before the circling began then this may mean it suffered head trauma at some point. Being dropped, grabbed by a dog, or crushed in a door or piece of furniture are all types of injuries that may cause head trauma.

Seizures are a symptom that will coincide with epilepsy, another neurological issue. There is no test for epilepsy. In these instances, continued close observation may be required and videoing any unusual behavior could be helpful for your vet.

Treatment of Circling in Hamsters

Persistent or severe circling in hamsters always merits a visit to your veterinarian.

If the behavior is caused by an ear infection, antibiotics that are safe for a hamster to take will need to be prescribed as treatment. Without them, permanent damage can occur to your hamster's ear and the circling may never stop. Infections can also lead to more serious complications that, in extreme cases, can be life-threatening. Oral antibiotics and sometimes pain medications may be needed to treat the infection. If ear debris is visible a gentle cleaning may also be helpful.

If the circling is not due to an ear infection then it may be more difficult to treat. Brain damage from seizures or head injury can be permanent. Some circling will resolve over time on its own but some hamsters may have permanent circling. If the circling is so bad that it affects your hamster's quality of life and it is unable to eat then euthanasia may be discussed.

How to Prevent Circling in Hamsters

Hamsters are small pets that like to hide. It can be difficult to notice when they are acting a little strange in their cages, but regular observation of your hamster's normal activities can help detect the beginning of a problem. This, along with regular cleaning of the cage and washing of the cage accessories, can help prevent ear infections that cause circling.

In order to prevent head trauma that can result in circling, be sure to only allow children to handle your hamster when they are sitting on the ground. This will decrease the likelihood of your hamster falling and getting hurt. When the child is done holding your hamster, either bring the cage to the floor to put them back in it or gently take your hamster from the child so that you can carefully put it back in its cage yourself.

Keep your hamster safe if you have dogs or cats in the house when they are out of their cage and make sure that their cage is secure and locked over at all times.


Accidents can happen but they are far less likely to occur if you supervise carefully and take extra precautions.

How to Clean Your Dog’s Ears

Keeping your dog's ears clean and dry is an important part of keeping them healthy and happy. In this article, we explain how to do an easy-does-it ear cleaning.

Have you rubbed your dog’s ears today? Sure you have. It’s one of those things we do almost mindlessly, relishing their softness and our dog’s positive response. But did you know that rubbing your dog’s ears is also a great way to make sure they are healthy? Think about it. If your dog enjoys having them rubbed, you can tell their ears are healthy. If they’re tender from an infection or injury, your dog may pull away from you, unwilling to have them touched. Gently massaging your dog’s ears is a great first step toward checking their condition. If you notice that they are sensitive about having them touched, it’s time to take a closer sniff.

Sniff & See

Yes, sniff. Healthy ears don’t have an odor. Make a habit of sniffing your dog’s ears, starting when they are just a puppy, so you know how they smell normally. If their ears smell yeasty or downright stinky, it’s likely that a bacterial or yeast infection is brewing.

Then take a look inside their ears. The skin should be nice and pink with a light coating of pale yellowish wax. A small amount of wax is part of the ear’s self-cleaning system. If the ears look red or have a dark brown or black discharge, or if your dog frequently shakes their head, paws at their ears, or rubs them against the carpet or furniture, they need a visit to the veterinarian to see what’s causing the problem.

How do you know if your dog’s ears need to be cleaned? If they look and smell good, leave them alone. In fact, cleaning a healthy ear can damage its self-cleaning abilities or irritate it.

Clean the ears yourself (see the step-by-step directions below) if they have a mild odor and you see an occasional head shake. That may be enough to stop an infection before it takes hold. You should also clean the ears if the wax looks dirty gray instead of golden or if the ears look waxier than normal. When too much wax builds up, it can block airflow in the ear and lead to an infection of the outer ear canal.

When it comes to dogs and cats, ears are much the same. Both species get the same allergies and infections. Cats, however, are more likely to get parasitic infections (preventable with monthly or quarterly topical medications), whereas dogs are more predisposed to allergic ear disease.

Avoid Ear Infections

Take your dog to the vet if the signs—or smells—continue or worsen after you clean their ears. They may need a deep cleaning and antibiotic drops or ointment to resolve the infection.

Some dogs are ear-infection magnets. If you have a floppy-eared dog or a dog with a history of ear problems, check their ears weekly. There’s no scientific evidence that dogs with droopy ears have more ear infections, but anecdotally they tend to be the ones that veterinarians see more often with ear infections. That said, allergies are probably the main cause of ear problems, and they are seen in dogs of all types.

Your best bet for preventing ear infections is to keep your dog’s ears clean and dry. Bacteria and yeast love a warm, moist environment. Keep them at bay by drying your dog’s ears thoroughly after a swim or bath.

Step-by-Step Ear Cleaning for Dogs

  • Tilt your dog's head downward with one hand and squirt a gentle cleanser (ask your veterinarian for a recommendation first!) into the ear, filling the canal.

  • Using the flap to hold the ear closed, give it a nice massage—which will squish the cleanser around and soften any gunk inside.

  • Step back and let your dog shake. You may want to hold a towel between you and your pooch so you aren't in the splash zone.

  • Wipe away any remaining cleanser with soft, dry tissue, not going any deeper than your first knuckle. That’s all you need to do. (Don’t mess around with cotton swabs that can drive debris deeper into your dog’s ear or q-tips that can drive it down further or do damage to the inner ear.)
