No matter what you have heard, it is not true that small toys dogs such as the Pomeranian are "snappy". This is a stereotype and for this reason, owners should not accept the biting or nipping behavior is a 'breed trait'. The Pom breed's ancestors originated in cold climates as they were sled-pulling dogs whose average size was 30 pounds. Over time, they have become smaller dogs, but this did not make them biters.
A small dog does not need to live up to its infamous reputation of being a snappy dog. A Pomeranian can be cute and friendly and just as wonderfully trained as any other type of breed. The key is the word train.
Just as a child needs to be shown how to do things and a toddler needs to be shown what is correct behavior and what is not, your Pomeranian needs to be shown what is correct behavior and what is not acceptable.
Not matter how long a dog breed has been domesticated, canine instinct prevails. To a Pomeranian, his pack is his human family (and any other pets in the household). His humans are his pack leaders - though some dogs do see children as peers.
One of the fastest methods to teach a dog to stop biting is to quickly show him that biting will equal a temporary banishment from the pack.
The order of training is:
1. Immediately distance yourself from your dog
2. Immediately ignore your Pom - This means 100% ignore. Zero talking, zero eye contact. No interaction at all.
3. Continue this until your dog has noticed. You will see that he becomes a bit whiny and may pace. It is at this time that his mind is metaphorically thinking, "Did I do something wrong to be ignored by my pack leader? Oh, no, I'm being ignored... am I being banished?"
4. After a few minutes, all casual contact (no praising or patting yet), however an owner may speak out loud, etc.
5. If a Pom nips again, immediately go to Step 1.
6. If a Pom behaves, offer great praise and a treat
It can take days to weeks for a dog to learn to stop biting; however once it is learned, treats will not need to be given for good behavior; though occasionally vocal praise will encourage a dog to continue behaving nicely.
