I have adopted a male dog (entire) and now my female husky (speyed) is constanly humping the malamute! why is this, is it a domination thing or is she confused? He just lets her do anything to him!

We have both Malamute and a Siberian husky and they are great mates, both have been rehomed with our family as adult dogs.
It just takes a bit of getting used to the size of a mal and picking up dino sized poos!lol
Both breeds are very swee...
