Our Working Cocker girl is now just over a year old - she is incredibly intelligent and can (when she wants to) follow all the commands, sit, stay, leave, wait, etc., etc., plus more advanced like "find it" in the house when we hide treats for her. We have been to basic puppy training and then one to one sessions with a gun dog trainer as well so we have put a lot of time and effort into training. She has always had a strong desire to investigate other dogs, other people, bikes, helicopters, horses, strange noises or anything if off lead but wasn't too bad at coming back up until a couple of months ago. Now it is so bad that our trainer has said she should be kept on lead and gradually build back up, which we have been trying to do. Trouble is the main thing that absolutely gives her the best time is to run as fast as she can (and she is really, really fast) - she'll hare off and although doesn't disappear from sight she is completely out of control - loops round other dogs or anything that catches her eye. We have tried everything, very tasty treats, squeaky toys, balls, hiding, running away - etc., We are booked on a Recall Masterclass course next month but is there anything else anyone can suggest as we'er at our wits end to know what to do. Please help!
