We have two wolfdogs in our appartment, both females, no problems after around 12 months of age - before that it took some training and the chewing around of some stuff (mainly anything which contained food, leather items such as shoes and leashes, socks and kitchen rags, though other items which came within reach would definately be an issue) Wolfdogs can be kept in appartments, we do it - and it does seem to help with their socialisation to some extent however, I am not certain it is ideal, and it does require a lot, and I mean really a lot of work for you to be able to really leave the wolfdogs alone in the appartment and go out for a walk.
As for reading - that would largely depend on your language skills, as books about wolfdogs are not actually available in english. Otherwise learn all you can about socialisation of dogs and living and training with them, I'll ask Mirka to pop in and give you a bibliography. (Its too late and I'm too lazy)
Cheers
J.
