I think I misunderstood you. If you are interested in socializing him, allowing him to approach and play with other, non-threatening dogs will help him lose his fear of them. Taking him for very short, very frequent visits to the pet store where a lot of dogs are usually restrained on leashes or in arms or carts might be a start. If he shakes dreadfully, some private sessions playing with another single dog might help him begin to adjust to another dog and then take the two of them walking together or meet up on a few walks.

Desensitizing him to allowing strange people and dogs to pass might be helped if you took along a pouch of boiled chicken to treat him and keep his attention on the food while others approach and pass w/out any bad thing happening to him at the same time he's being offered delicious, warm chicken to snack on. In time, he could associate people and dogs approaching with good things happening and begin to accept them as you keep on working with him. In time, if he begins to stop shaking or acting nervous as they approach, asking them to stand still and allow you two to approach them and walk right by for a few times might show him there is nothing to fear and make him wish to stop one time and sniff butts and begin a visit with another dog.

Many dogs are more fearful and nervous when on the leash when encountering strange dogs as they feel like victims on the leash - sensing they are captive to it and subject to anything that other dog or person might want to do to them. The best way to warm two dogs up to each other is to allow them to approach on leash, watch their body language to be sure no fight is brewing and then, unleash them both if you are in a fenced area. That way neither of them feels constrained or victimized by the leash keeping him from defending himself and he's way more at ease with a strange dog, realizing he's free to meet, sniff, play, run or rise up or fight or whatever he might need to do to protect himself, so he's not in a frozen, anxious or belligerent mood, he's more relaxed and naturally friendly with another calm, submissive dog.
