I have a 16-month-old Shar Pei cross (rescue dog) who has recently (last few months) become overly fearful and/or protective when visitors come near or into our house. She will bark at them and growl and she has on a few occasions nipped at people entering our home. She has only had sporadic training but will respond to 'come' and 'sit'. I am wondering if following the Brain Training course will help with her aggression issue or if she will also need behaviour modification to deal with it.
I will start with the course now (as she needs the training) but should I wait and see how she responds or should I contact a behaviour specialist now as well?
