bonnie north Plains, OR 2/28/2009 2:08:50 PM We have tried everything you mention but our 9 month old labradoodle still chases our cat without mercy. The cat also taunts him, so we have double trouble. The cat is 15 and has lived peacefully with 4 other dogs in its past. This is the first time we've had this trouble. Any other suggestions to get our dog to stop chasing the cat?
