Puppy got too much ear cleaner in ear. Is it harmful? What to do?

Do not worry, nothing bad will happen, basically what it states is that she needs at least 4 drops for it to be effective, putting in more will not harm her but the bottle might finish sooner than expected because of that.

Rinse Sam's eye with cool water as well. Monitor it for redness, swelling, discharge, or pain. He would show pain by keeping his eye closed as much as possible and/or rubbing at his eye. If you see any of those signs, have him seen by a vet. Best of luck.

Do not worry, these formulations are very safe and act locally, even if you apply much more than you should, your dog will not be in any danger, the only problem is that you might finish the drops too soon if you use too much and you might need to buy another bottle from your vet.

Hello, thank you for using Petco Pet Education Center, formerly Petcoach. Baby will be just fine. There is no harm in putting more than the prescribed amount of medication in the ear canal. It is just a waste of the product. Don't worry about this at all. Hope this helps. Best wishes.

Yes, a small amount can be applied to the ear canal and/or a cotton ball. Gently clean the ear with a dry cotton ball afterwards. Sometimes, tilting the head so the ear being cleaned is pointed down will remove excess liquid in the canal.

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. I'm sorry to hear that Cookie yelped and vomited following her ear cleaning. The inside of dogs' ears is very sensitive, and we NEVER recommend cleaning their ears with Q-tips, for risk of causing damage to the ear drum (tympanic membrane). As long as she is acting normally at home (no head tilt, not ear scratching or head shaking, eating/drinking/urinating and defecating normally), she will likely be OK! From now on, please only ever clean her ears gently with a dry cotton ball, and only clean the visible, external portion of the ear canal. I hope this is helpful!

Nope, I would definitely stop that. Ears naturally clean themselves and don't need cleaned unless there is an issue. If you're seeing redness, brown/black discharge, an excessive amount of wax, or Lady is rubbing/scratching them, she needs to go to the vet to have them sampled and appropriate treatment started. Unfortunately, she could actually get an infection from the hydrogen peroxide you've been using, so definitely keep a close eye on things right now. The good news is that ear infections are very treatable with proper medications from the vet.
