hi there, how is Freya around kids and other dogs and cats? I have 2 kids, a 14 year old cat and adopted a n old mix breed dog (8 years old) last year and they are great, looking for a younger dog to join the family, I have a small garden but not sure if Freya will be too active (requiring more space) Looking for a trained (guard) dog that can have fun with the family and watch over them while I am not around them. is she "toilet" trained? does she shed a lot?
