Quick answer: Puppies commonly get ear mites and ear infections. Ear mites cause intense itching and dark, crumbly, coffee-ground debris, and spread easily between pets. Infections cause redness, odor, and discharge. Both need a vet diagnosis, since treatments differ. Puppies with floppy or hairy ears, and those that swim, are more prone to infections.
