What kind of medicine is itchy in the dog's ears, and the ears are almost caught. Is there a solution?

Please help me who can help me summarize the common sense of raising cats and dogs, that is, they usually pay attention to sending them to the cat -raising people in the community.

Is it okay to be more than 500 Alaska dogs? Just play by myself, but to be tall and tall, don't see at a glance, because I have seen the kind of cheap dog with a long dog face but a thin, too awkward.
