If I had a ยฃ1 for every time a dog trainer posts on social media that socialisation is BAD for your dog, I'd have enough to open a dog dating website.
Your dog is NOT reactive because it met some other dogs on lead when it was young. This has become one of those 'facts' that's been repeated so many times, everyone takes it as fact now.
They're NOT reactive because they were allowed to play with other dogs when they were a puppy.
๐กSocialisation actually means two things:
1) It's a period in a puppy's life when they are open to new things and experiences so that they don't become scared of stuff they'll encounter in their environment daily (like if they got scared EVERY morning when they saw their mum, it wouldn't be very useful)
2) It's an evolutionary mechanism which, when that window of openness closes, it makes them wary of new stuff so that young dogs aren't trying to cosy up to bears or snakes in the wild...
So, during that short, short period (which has almost closed by the time of your puppy's first walk unfortunately), you should do all you can to get your dog introduced to lots of things you want it to be comfortable with.
That includes other dogs, people, children, scary noises and so on.
BUT...
Socialising with other dogs matters too!
โYou can't bring a dog up in complete isolation from other dogs, then expect it to not be INTERESTED in another dog when they see one on their walk.
โYou can't bring a dog up without ever having the chance to socialise, play, learn body language, and learn how to behave and expect them to one day just be comfortable and relaxed around other dogs.
Dogs learn an IMMENSE amount from other dogs.
Your dog playing with other dogs doesn't make them reactive when they're older.
What could have made them reactive to do with socialising is if you have never been as exciting as another dog, so when they do see a dog on a walk, that equals INSANE FUN, and your dog can become frustrated if they can't get to that dog, which can then result in reactivity.
But that's to do with not working on engagement and focus with you (which is an easy fix), not with socialising 'too much'.
