rules/warning/character details

it has been 3 months since rocky and tuck started dating and rocky has been the happiest pup of his life. when the 2 got married, Ryder got them a new pup house with lots of new things for them such as a tv, a couch, even a 12.6 sized bed for them. with their new born daughter "tundra" they start to be more happier with each there. but one day, a wolf is trying to ruin the family. who is this wolf and what does he want from the 2? (yes these pups are still the same age as in the tv show and the previous rocky x tuck love story so do not question me that's just the script)
