A friend recently got himself two growing Alsatians- male and female about 5-8mths old. He is determined to make them mean and ferocious so they are kept in strict isolation. Initially they were kept separate but he felt this might hurt them emotionally and in turn affect their overall growth hence, reversal.
He has not heard anything that even mimics a bark and they notoriously court affection always. Useful tips on how to turn these wimps into effective security dogs are welcome. My friend is not a pet-keeping kind so a role change for them is not an option.
