Dogs that get on with other dogs are the best kind. My dog Milo will be fetching a ball but if he sees ANY other dog he'll veer off and approach them to play with them, he's silly. Even if he has to run the length of the park. They aren't always best pleased to see him though! I've got pictures of him on my blog (labradoodle).
That's exactly how mine is.. Your dog is quite handsome looking and has that look of "play with me"
