[Blue gumdrops]

So I've had him for awhile and he always tried to bite my hand and I correct it and say no in a firm voice but he continues. I've tried yelping in a high pitched voice and he continues. I've walked away from him so he knows that he lost his buddy but when I come back he continues biting even when I continue this process. He bites everyone and everything. When I'm walking he tries to play tug a war with my shoes. And never releases and growls. He even has things in his mouth like paper and when I try to take t away he runs and squirms when I have him. I've token it out of his mouth but he bites me to the point where I'm bleeding. This is the first time he's done it to me but he's done it to my sister. It hurts and I want this to stop. What can I do? I'm running out of options. Btw he's 13 weeks old
