bad dog behavior that needs to stop

hi my name is Ryan i have a staffy cross called Logan he is just over one years old.

the bad behavior is that he jumps up at people when anyone enters the house, he mouths really hard were it leaves teeth imprints, he barks all the time for no reason, he jumps up at people when there in the house and sitting down. he bites and pulls clothes and shoes.

i know he is still a puppy and we got him when he was about 7 weeks old and was great for the 1st 6-7 months then he started doing all this. i have tried loads of different training methods and nothing seems to work.

i take him out for atleast 1 and a half hour walk and then play fetch with him for about 30 mins in the garden every day.

the reason i need help is because the people we are living with, one was diagnosed with motonuron disease and he is really unsteady on his feet now were the muscle are wearing away. i don't want to have to give him away he is my best friend and i love him so much.

please can anyone help me with tips or links to videos they found helpful.
