Aggressive Chihuahua Dachshund Mix

I've had my puppy for a week, he was 8-9 weeks when I got him and he has been showing signs of aggression.

When I try to play with him, he likes to jump and snap at my face. He always shows teeth and has started growling even when I just want to pet him, he tries to bite my hand. I'm not sure if its because he's uncomfortable or if it's something else.

I've tried the time out method, and the ouch method but it doesnt work. He still jumps at me. I'll be taking him to the vet as soon as I can, but for now, I'm very scared to play with my little pup.
