My lot do associate willy nilly with the dogs we meet, it has taught them to understand other dogs, they will play with those who want to play, exchange pleasantries, or have a quick sniff with the dogs they meet, depending on the other dogs stance.
When they are young and do not yet know the social graces I encourage lots of calm controlled meetings with other dogs, so that when they are loose they do not get too excited and overpowering. Mine is a medium sized energetic breed, who do not naturally stay close at heel (understatement), they have never had a fight, have been set upon once or twice, but having stood their ground, and having had the other dog removed proceeded on their way, and have never borne grudges. They are confident, so do not seem to need to prove dominance over others, nor are they afraid, if a dog is aggressive they will avoid it, unless actually attacked when they will defend themselves, but happy to leave it at that once the other dog has stopped. I have travelled to shows and visited other canine households with all manner of breeds, from Dobermanns to Italian Greyhounds!
I know it is not natural for Canids to accept non pack members as friends, but we have changed our dogs quite a bit with domestication, and increased tolerance of others of its kind is part of this. It is also unatural for bitches and dogs to mate with others of the opposite sex willy nilly, as in the wild only an Alpha pair breed, but they do! We take our dogs out in Society, and the better they get on with other dogs, and the more positive experiences they have, the better proofed they are against the occasional not so good experience. Also a dog confident in this way is less likely to be picked upon by canine bullies, who in the most part are this way due to lack of socialisation.
I have a friend who's Golden Retriever bitch would bite any dog that came in reach! she had her at 1 year old, and she had not been socialised. when I kept my first puppy we met her and she fell in love with the non threatening pup. She learnt to play at 3 years old! We then introduced her to the pups mum, who she went for when the pup went to play with Mum. She was told off (my bitch had defended herself, but was happy to make friends) by the Humans, and we did not split them up, but kept a watch on any further interactions. she soon accepted Mum too. After a few months of socialising with these two I gradually allowed her to meet with nice dogs in the park, watching that she didn't snap. Now this bitch is reliable with other dogs, will tell off young Romeos or over bouncy youngsters in quite a restrained fashion, but mostly acts superior, with her nose in the air. She is now so confident that she sees no need to worry, and has no bullying tendencies either. Her only problem is that at 9 years old she still thinks she is a puppy 9missed out on childhood) and I have to save her from herself, as she had hurt herself twisting and playing with young dogs, last year she tore a ligament, and had to miss out playing with my full grown exuberant 'boomerang' bitch, she is now staying with me for a week, and now that the youngster is more sensible I have no fears for her.
My youngest is now nearly two, and came back to me at 8 1/2 months old, so she did tend to be a bit pushy at first (no prior training) but my own dogs soon taught herhow to behave with her own kind by telling her off, so apart from at first being a bit noisy when meeting other dogs, asking them to play from a few feet away, no problems with other dogs! A problem i had for first few weeks was overexuberance with any person who made eye contact with her, she would tigger them! This only happened if the peopleacknowledged her in some way. after effusive appologies, and more training, she now responds well, even at distance to the command of Steady!!!
