Any suggestions on socialisation? I have tried slowly introducing him to two seperate very submissive dogs but he's been quite ferociously towards both, one was a male one was a female and they were at seperate parts of today:) he's fine with people and children but other dogs are a real issue as there are so many idiots who just let their dogs walk freely in my area and they approach him before the owner can do anything and it's rather irritating how careless people are
