My 13 month standard poodle cross has recently started barking at people/dogs if they surprise her. Ie if someone comes in she wasn't expecting or in a pub if she suddenly noticed a dog nearby. Today in pub she was horrendous and the man she barked at was a twat who thought it funny to bark back
. Any advice? Do not want this getting worse, I was mortified today and if we hadn't already ordered I'd have left.
