Pomeranians are generally a very healthy, hardy and long-lived breed — often, Poms live 15 or 16 years. As with any breed of dogs, however, there are certain problems that may be encountered.
The most commonly occurring problems involve the teeth which, if not scrupulously cared for and maintained through frequent cleaning, can fall out at a relatively early age, possibly causing heart problems leading to early death. It is also important to keep the Pomeranian's toenails short through regular trimming (at least every 2-3 weeks). They are quite a hardy breed, requiring little in the way of special care but they do require lots of love and attention. A Pomeranian's greatest joy in life is to be near the object(s) of his devotion.
This is what I found to be important. For mantaining the teeth I suggest that your give your little one a bone to chew. Not cooked.
You will be a good team.
