I knew this was going to happen?

I failed my dog. He's a one year old almost 2 year oldlabradoodle.

He jumps up on people, pulls on leash while walking, gets aggressive with other big dogs and goes NUTS in drive thrus. He is okay around smaller dogs.

I think he's aggressive, he's unaltered.

I'm going to be honest, I didn't really socialize him as much as I wanted to. I didn't really stress it a lot. He's smart, he knows to sit, lay down, wait, spin and shake. I taught him all of those. He's also displaying resource guarding.

I feel like a shitty dog mom, because now I can't really take him anywhere. Is this fixable?

I failed him, I really did. I love him so much, he's so loyal to me.

If I take him to the dog park will this fix it? Or keep exposing him to dogs? I'm just confused on what to do. I failed him so much..
