It seems that Storm is one of the only dogs who accepts Arrow, so I think they may become mates. Sweet and Lucky are already mates, and I'm guessing that soon in TGD series they will have pups. About Blade and the rest of them, Fear-Dog may bring back dogs like Alpha, Fang, Blade and them. I think Terror may be alive, and the other dogs like Alpha and Fang and Blade may join him and there could be another battle.
Thanks for reading!
