Usually, wolves will get along with other wolves, (like packs) but if a wolf wants leadership or a lone wolf comes near, they will usually attack another wolf.
By scent. Each wolf has a different scent. Rarely a wolf can tell a pack member by a characteristic they have or how they act within the pack. But mostly by their scent.
Depends on how they help each other. In a pack or separate lone wolves?Pack--they hunt with each other, play with each other, clean each other, show affection, show loyalty, mourn.Seperate--very rare...
Probably because some guttural Russian calling Brother Ralph was surprised to find the wild dogs closing in. Volf, Volf where are you? Why is a verandah called a veranda?
