|It's not 'normal' as in something that should be accepted, but I've worked with a LOT of small breed puppies that behaved that way.
If he were a four month old rottweiler puppy, I think you already would've answered your own question because of the damage he'd already be capable of inflicting.
You really need to take steps to end the problem. I recommend getting a good trainer, if you're unsure how to proceed on your own.
The thing about small breed biting puppies is that they grow up to be small breed biting adults. At the grooming shop where I used to work, there was a shih-tzu who had sent three different groomers to the ER for stitches. The least was four, the most was six. Honestly, that dog wouldn't have been welcome in my establishment without more training, but as an employee I was just subjected to what he wanted to dish out.
Beyond making his vet, owners and groomers miserable, this dog had a very poor quality of life because no one wanted to pet or cuddle him because he bit. He had to be completely sedated for a full groom, and his owner couldn't brush him because of his biting...nor could you clip his nails without him being sedated. As a result, he came in every six months matted with sores and his claws growing into his pads. His owners didn't want to train him because training him would've been 'mean,' because he was 'feisty' and because it was 'cute.' The dog got to the point at which he would pull a muzzle off or struggle so hard you couldn't do anything with him.
Now, I'm not trying to scare you or make you feel bad. You're taking a step in the right direction any time you get help for a dog's bad behavior. The puppy is young enough that it should be easily fixable and within no time, you should have a wonderful companion.
Gir, for example, behaved much the way your puppy does when he was young, and he's now a truly incredible dog.
