I just adopted a 3 year old pitbull. We took it to the vet and they said it has an ear infection, but I assume the ear infection is probably deeper in the ear as I cannot see it in the visible areas. Moreover, the dog doesn't seem to be in pain nor does he scratch his ear. So I'm not sure if this ear infection is that severe. But the vet still suggested an ear infection treatment and the bill comes to about 150$. So I'm hoping to treat it myself.
I bought hy-otic ear rinse and am planning to give its ear a good cleaning, based on some tutorials by vets on Youtube. But after that, what's the best way to go about doing something regarding antibiotics/medication, etc? Is there any good remedies?
Note: The previous owner had cut its ears short when it was a puppy apparently. For the last year or so, before he came to the pound, he's been a stray - hence the ear wax build up.
