Short answer

Yes, it's possible. Check for chewed-up bottles under furniture, especially in bathrooms or grooming areas where you store pet supplies. These solutions often contain alcohol or chlorhexidine, which can cause mouth ulcers, vomiting, and loss of balance if licked. If you find a damaged container or see your dog drooling or pawing at its mouth, contact your veterinarian right away. Do not induce vomiting; if you can, gently rinse its mouth with water and bring the product to the vet for identification.

Where an 8 kg dog might find hidden cleaner

Dogs often nose into unexpected places—check behind toilet bowls, under bathroom cabinets, or tucked beside grooming kits where bottles could roll. Cocker spaniels are particularly curious, and their floppy ears might make them more likely to investigate ear-related products. The smell of alcohol or antiseptic can attract them even through closed containers.

Look for puncture marks on plastic bottles or chewed caps, which would confirm exposure. A missing bottle doesn’t always mean ingestion; some dogs just shred things. But if you find a damaged container, estimate how much might be missing to help your vet assess risk.

Why size matters with alcohol-based solutions

An 8 kg dog is small enough that even a few milliliters of alcohol can cause noticeable effects. Unlike larger breeds, their systems can’t dilute toxins as effectively. Watch for early signs like excessive drooling or rubbing their face against furniture—this suggests mouth irritation from the solution’s ingredients.

Balance issues would appear within two hours if the alcohol affects their nervous system. They might stumble or have trouble jumping onto furniture. Don’t wait for these signs to call your vet; describe the bottle’s ingredients if you still have it.

The danger of chlorhexidine in grooming products

Many ear cleaners contain chlorhexidine, which is safe for external use but harsh when swallowed. It can ulcerate the esophagus, causing pain when swallowing. Your dog might refuse treats or yawn repeatedly from throat discomfort.

Vomiting after exposure is especially concerning with chlorhexidine, as it can re-expose the throat to the irritant. If your spaniel vomits more than once or produces frothy bile, skip monitoring and go straight to emergency care. Bring the product label to help the vet choose the right treatment.

When hidden exposure turns urgent

If you can’t find the bottle but notice your dog acting oddly—like sudden lethargy or disorientation—assume they ingested something. Time matters with alcohol absorption; their small body weight means symptoms can escalate quickly.

Check their gums for unusual redness or dryness, which indicates systemic irritation. Even without visible bottle damage, a vet visit is wise if they show these signs. Describe any other products stored nearby in case it wasn’t ear cleaner but something similarly toxic.
