Thanks to you both, I'm a bit less anxious now knowing I'm not alone! Yes, he is neutered, Rona, he was done about 6 weeks ago, but he lives with 2 foster GSDs who act very boisterous (not aggressive though, they want to sniff) around other dogs so I doubt this helps. He went to the beach last week & we spent the day with my friend's standard poodle who is 12 & pretty laid back & Bob was fine, he also played quite well with a female GSD Husky mix we met. I'm thinking of trying to distract him when another dog approaches & when he passes with no incident offering praise & a training treat. It's a nightmare having a teenage dog AND a teenage boy in the house!
