Wolves in general

Avoiding of inbreeding. How is inbreeding avoided, if a pack is a family and only a few wolves immigrate?

Inbreeding indeed is often seen in isolated wolf packs and only occasionally a wolf from outside is able to integrate in a pack. zucht ist gerade bei isolierten Wolfsrudeln häufig und nur gelegentlich schafft es ein Wolf von außen, sich einem Rudel anzuschließen. It's more like that young wolves migrate, find partners for pairing and form new packs. Wolves and dogs are relatively tolerant against inbreeding, but after a couple of generations signs of degenerations will occur leading to the break down of the pack.

Are there really wolves, who never in their lives will breed and also do not try to become alphas?

That's possible, as a pack is strong related social system and in a stabile pack hardly a wolf tries to challenge the Alphas.That's different at ther death. Since normally the animals in a stabile pack highly related to each other they contribute to their own fitness, when taking part in the care of the progeny or their siblings (Concept of "inductive fitness").

How fast is a wolf?

At a trot about 15 km/h, in full speed running (galopping) about 40 km/h, sprinting more than 60km/h. Concerning the speed wolves are not at all top persormers, but they are able to chase their prey in a smart trot or an easy galopp over long distances, without tiring, for they are specialized running hunters („hypercursorial hunters“).
