I need help 😭

I have a 4 month lab and he’s honestly wonderful except for when we try to take something away from him.

It’s been a behavior we have noticed but essentially we take an item he isn’t supposed to have he goes crazy and literally bites up my arms. It’s honesty scary because he is a 40lb pup. And he is only going to get bigger. Today he tried to grab the shoe I was wearing and when I said no, he got agitated. He kept jumping and coming at me for about 1 minute.

I know that might not sound like a lot but I kept pushing him away and I try to walk away but he just doesn’t listen. I honestly don’t even have the opportunity to walk away quickly because he just so fast. He keeps coming at me over and over again. He uses his teeth to scratch my arm. I know he’s a puppy but literally feels like an attack. My arm is literally scratched up and a bit bloody now. Idk how much longer we can keep up with this.

I really need some help and advice on how to get him to stop. We love him so much but seriously he’s getting big and we don’t want it to get worse.
