Don't go deep into the ear canal. You can seriously hurt or injure your puppy if you do so. The folds or crevices can be cleaned using a cotton swab moistened with water, mineral oil, or isopropyl alcohol. If you ever see that your puppy's ears are red, inflamed, swollen, sore, or if there is a foul smell or discharge, your puppy probably has an ear infection. We recommend that you take your puppy to your veterinarian for a thorough examination.
Ear infections are relatively common, and are easy to treat if noticed early.
But if you ignore it, it can rapidly worsen to a serious condition. Attending to your puppy's mouth and teeth now will get him used to having his teeth and gums brushed later on. We included putting your hand in his mouth as part of dog massage earlier in the course. You can gently rub a recommended dental care product across your puppy's teeth and gums using your finger. Most people neglect nail cutting because they do not know how to do it, or are afraid.
