Can you train a 10 year old GR?

[NoCoco]

I have taken on a 10 year old GR, he hasnt been socialised at all.
He is now ok with us in the house but when people visit or we are out for a walk he jumps at everyone and barks at people, dogs and cars.
Is it too late for training him? He isn't very interested in food rewards, well only for a very short time. He's well toilet trained, sleep trained it's just that he isn't socialised at all.
I'm not too sure how to address this?

Well you've taken him on so you're going to try to train him both for him and you .
I would work out what's livable with and ignore that just now
Focus on the really important stuff .no-one wants jumped on when they're walking past a dog so that would be my first goal
4 feet on ground and can practice at home as well .
Teach the bark on command then weirdly the quiet one seems to make more sense.
Good luck and hopefully all goes well

Yes. You can teach any dog. I just had a successful rehome of a 12 year old Golden. Bite history. Severe SA. Reactivity. Resource Guarding. Jumping at strangers. Lunging. Literally everything a dog could have wrong with it, he did! It took 8 months to find a family capable of building on what I started with him.

You need to start slowly. Take him out during quieter periods - I was out at 04:30 with mine. It's painful. But you can't overstimulate them. So earlier and later is better. That way you stand more chance of successfully diverting his attention away. When you see someone or something coming that early, pull him to the side and give him a treat.

I would stop having visitors as well. Sorry, I know it's not what you want to hear. But rescue dogs can be really difficult to settle - particularly ones who have had difficult lives (which yours clearly has). In a good situation it can take 3 months. In a bad one? Years. Bringing people into a home he's not familiar with is going to scare him and lead to bad behaviours - potentially dangerous ones.

I'm really interested in how you got him though? Was this a private rehome? A good rescue should have thoroughly vetted you and the dog to make sure you're a good match AND be giving you ongoing support.

I think you can. Focus on developing a bond first and foremost. GRs love to please. Ours is not food orientated but a squeaky toy or ball is a very high value reward. Take it slow with lots of love. Good luck
