no absolutely not. in the first place ear mites in animals aren't usually treated with oral antibiotics. in the second place you shouldn't have any "leftover" antibiotics to give your dog. whenever you receive a prescription for antibiotics it's crucial you take the entire prescription according to the label instructions. if you stop taking the antibiotics before they're all gone it may contribute to the rise of antibiotic-resistant germs like mrsa. please don't ever try to "save" or conserve antibiotics for another illness. you need to take them all. but back to your dog. it's impossible for a lay person to diagnose ear mites. this diagnosis requires an examination by a veterinarian using a lighted scope and other diagnostic tests. please take your pet to a veterinarian if you believe he has a health problem.
i'm pretty sure that my lab has ear mites. can i give him human antibiotics
