Hope everything goes well with your puppy,it's always difficult trying to help creatures totally depended on you.
But is a small price to pay considering the love they give you.
Absolutely correct.Amir, I have a lot of experience giving intravenous Gentamicin but less with Gentamicin ear drops. I can tell you that ototoxicity (i.e. toxicity to the hearing and balance organs) is rare with intravenous Gentamicin, because we carefully monitor the levels and kidney function while we are giving it. Just FYI the typical dose is 5-7mg/kg rounded to the nearest multiple of 40mg, so a 50kg person would get 240mg. Ear drops are a different story, levels are not monitored, and despite much lower doses being given, ototixicity is more common, although I do not know how common. I did a literature search for you and I found this paper, which is a review of ototoxicity from Gentamicin ear drops. It looks like they don't know either
I agree that if your dog has developed hearing loss from both ears, it is unlikely to be from an ear infection in one ear.
I also agree with your vet - once hearing loss has developed, the only recourse is to cross your fingers and hope it comes back. There have been some studies trying to reverse the hearing loss by giving antioxidants but there is no evidence that this works.
It's a good thing there was no cochlear toxicity as well (I am guessing not, since you don't report your dog walking like a drunk and falling over). That would be truly miserable.
Best of luck to you and your dog.
Hey Amir, was just wondering if there was any further improvement?Today we have noticed a change in that he appears to be occasionally responding to louder, higher frequency sounds. He is so good at reading body language (and following the reactions of his sister) that it is hard to know if he is really hearing something or not.

Ours ate part of a wall when he was a puppy but then took extremely well to training and has been excellent in that regard. We have two and they are very well behaved as dogs go. They even know not to climb up to the loft where my lab is without any kind of gate!He was naughty, shredded all the curtains in the front rooms of the house while his owners were out. But he was beautiful. I used to ride my scooter down the street hoping he’d run to the front gate. His fur was amazing when I felt it through the bars.
Wow, that is what happened! Wish this was in the notation for the version of the drug we gave him. Ours just said older dogs may suffer hearing loss and that was that.I found this in the notice of one of our treatments for otitis containing gentamicine :
In very rare cases, the use of the product may cause hearing impairment (partial hearing loss or deafness), especially in older dogs.
Based on post-marketing safety experience, improvement in hearing was observed in most dogs with deafness/hearing loss and full recovery was confirmed in 70% of dogs case with adequate follow-up.
In fully recovered dogs, improvement was seen quickly.
Recovery was observed as early as a week after the onset of signs, with the majority of dogs recovering within a month; in a minority of cases, deafness lasted up to two months.
Yes, post creating this thread a friend doctor suggest that he may have lost his hearing prior to even giving him the drops. I had not thought of that and keep wondering if the infection (or previous treatment) caused it. The change was so dramatic two days after giving him the drops that my mind directly went there. But it is entirely possible that the condition was there and hence was caused by the infection itself. We gave him the oral antibiotics the vet prescribed so maybe that fixed the underlying issue.Just as a potential, is it possible your dog had some hearing loss from this problem, but you hadn't noticed it and then when you gave the dog the drops, obviously this was a change, so you noticed the hearing loss and associated it with the medicine?
