With other dogs, not really, They do not need dog friends. They need me.
I used to take Sunny to the dog park but he hates it, all he does it bark at other dogs, chew sticks and then goes to attack another dog who touches his stick, he can't play with toys around dogs because he is toy possessive. Why risk it? I am not putting him in a situation he doesn't like. When I can drive, I will probably take him to the dog beach and give him a shot but we'll see. He does enjoy the company of one or two dogs so I'll give him some play time in the dog park when I can drive in the future but thats about it.
My other girl has fear issues and dislikes other dogs but we are working on this. She does get to meet other dogs, at times, for training.
I have no problem with my dogs meeting dogs but it isn't needed. I may take Sunny to the dog park sometimes when I go to take photos, if there isn't many dogs in there but thats it.
I feel more comfortable knowing my dogs are safer, not interacting with strange dogs.
