It’s concerning when your dog suddenly stops eating, especially if they’re also dealing with an ear infection. You might notice head shaking, scratching, or a foul odor from the ear — and now, your pup isn’t touching their food.
We outline the common causes of dog ear infection and not eating, what you can do at home, and when to seek veterinary help.
Dog Ear Infection and Not Eating — Why It Happens
Dogs with ear infections may stop eating due to pain, nausea, or systemic illness. Ear infections can cause inner ear discomfort, fever, or dizziness, all of which may contribute to a reduced appetite. In some cases, the infection has spread or triggered an underlying condition affecting your dog’s whole body. Stress, medication side effects, and general malaise from feeling unwell can also play a role.
Common Causes of Dog Ear Infection and Not Eating
Inner Ear Infections (Otitis Interna)
When an ear infection progresses deep into the inner ear, it can disrupt balance and cause nausea or dizziness — both of which can make eating unappealing.
Dogs with inner ear infections may walk in circles, tilt their head, or stumble.
Loss of appetite often goes hand in hand with these signs, especially if the infection has triggered a fever or systemic inflammation.
Middle Ear Infections (Otitis Media)
Middle ear infections can result from untreated outer ear infections or trauma.
They cause intense discomfort and can lead to facial nerve involvement, drooling, or difficulty chewing.
A dog in pain may simply avoid eating to prevent worsening the discomfort. You might also notice whining, irritability, or avoidance of petting near the ears.

Severe Outer Ear Infections (Otitis Externa)
Even outer ear infections can become severe enough to reduce appetite. The constant itch, inflammation, and pressure in the ear canal can be deeply distressing.
Add to that the side effects of antibiotics or ear-cleaning solutions, and your dog may feel too unwell to eat.
A foul odor, discharge, and redness are clear signs the infection has worsened.
Dental Pain Exacerbated by Ear Infections
Sometimes, ear infections coincide with dental problems — especially in older dogs.
Swelling or referred pain from the ear can make existing dental pain worse. Dogs may try to chew and then back away from food, or they may only eat soft items.
A combination of ear and mouth discomfort is a powerful appetite suppressant.
Fever or Systemic Infection
A systemic response to a severe infection can lead to fever, lethargy, and nausea.
If your dog has stopped eating and also seems warm to the touch or uninterested in normal activities, the infection may have progressed beyond the ear.
Loss of appetite is often the first sign that something more serious is occurring.
Medication Side Effects
Ear infections are typically treated with antibiotics, anti-inflammatories, or ear drops.
These medications can cause stomach upset or a temporary change in smell/taste, especially if your dog is sensitive.
If the drop-off in appetite began shortly after starting a new medication, side effects might be the culprit.
What to Do If Your Dog Is Experiencing an Ear Infection and Not Eating
If your dog has both an ear infection and has stopped eating, take action calmly but promptly.
Start by inspecting the ears for discharge, swelling, or signs of pain. Gently clean the area if advised by your vet, but avoid inserting anything deep into the ear canal.
Offer soft, bland food that’s easier to chew and more enticing, such as boiled chicken or rice. Warm food slightly to enhance aroma.
Keep your dog in a calm, quiet environment to reduce stress and allow them to rest.
Avoid touching the ears frequently as it may worsen discomfort.
If medications were recently introduced, call your vet to ask if an adjustment is needed.
Hydration is key — encourage small sips of water or offer ice cubes if your dog won’t drink.
When to Call or Visit Your Vet
Contact your veterinarian promptly if:
Your dog hasn’t eaten for more than 24–36 hours
There is yellow or bloody discharge from the ear
Your dog is in visible pain or cries when touched
There’s vomiting, diarrhea, or signs of dehydration
Your dog shows balance issues, facial drooping, or head tilt
The ear infection does not improve with treatment
These signs may point to a more advanced infection or a separate issue requiring additional care.

Key Takeaway
When a dog has an ear infection and stops eating, it’s often a sign they’re feeling much worse than they let on.
Whether it’s pain, nausea, or medication-related, appetite loss is always worth taking seriously.
Keep your dog comfortable, monitor their symptoms closely, and consult your vet if their appetite doesn’t return within a day or two.
With the right support, most dogs recover well and return to eating normally once the underlying issue is treated.
