I agree i would definitely get help with your Dobe, my bitch is fearful of other dogs she would bark/lunge, but she has improved dramatically by using the clicker, we got help through our vet using a apdt trainer. also tried everything else....but this seem to work for her, your girl needs to see dogs as a positive experience not a negative as already said. Hard i know, but it can be done :-) good luck with your girl.
