My little Chu.Dog has itchy ears and nothing seems to help

It might help if you described what you have tried. With some rare exceptions, most physical problems call for a vet visit. Most home remedies do fail.

There is basically nothing that you can but yourself that will take care of this problem. You first have to know the source which can only be attained by a veterinarian with a swab and a microscope! Ear problems can be from ear mites or fungal, bacterial or yeast overgrowths. Take him to the vet!
