I have had dogs my whole life, most of them GSD mixes, but never a pure bred. Didn't know what they "required", but I did know that a good diet, socialization, training, and vet care is needed and that is for any breed. Neither of mine get destructive if they don't get exercise, but will run and play any time they are allowed. They are well behaved and are loved. They are happy well adjusted dogs that succeed in everything I do with them.
