Dog Training Job - Greenside, GP, 2034

We have 2 miniature schnauzers, male 2 years old, female 18 months, both sterilised. Merlin is very friendly but has problems with some young male dogs that try dominate him. Lily-Belle is very protective and always tries to keep other dogs away from him and my wife. She takes on any size including Great Danes and we are worried that she will get hurt. She also barks at visitors to the home. We need help to get her more relaxed and friendly. Time is of the essence as we leave for the UK in 4 weeks.
