As some of you know our dalmatian Lucy was attacked at the dog park over a year ago and has become more nervous at the park and on walks as time goes on. Ever since we got our new puppy, she is now barking like crazy when our pool guy comes into our yard. The hair on her neck is up so I know she is scared and I'm guessing she is trying to protect our yard and the puppy. Can anyone recommend a good dog trainer they have worked with? I've called a couple trainers, but don't have any references. Thanks!!!
