The trouble with block is that it pushes you back out of swing range. By the time you move back in range they are swinging again.
I didn't know wolves could be tamed. I never in a million years would have figured out how to tame pigs if someone hadn't told me.
Tame wolves the same way you tame pigs, more or less, just with much bigger teeth- trap them somewhere and feed them, in their case any kind of meat that isnt wolf meat. Oh hey, a use for your excess pigs!

Unlike pigs though, wolves will follow you so theyre much easier to move to where you want them, or, of course, you can have them follow you in general as a mass of biting death to explain to your neighbors precisely how much you dont like them.

Send me a message if you want more info on wolf taming and how best/safest/easiest to trap them.
Blocking- as others have said, moving forward while blocking helps, but there are other options too- put your back to something solid like a tree, rock or steep slope so you cant be knocked back far, or use a knife and just special-attack after parrying to leap back into their face. Dont like blocking or dodging? The atgeir is your friend- go mobile and use its longer reach and the special attack to thwack them before they can hit you, which knocks them back and often staggers them for a follow-up. Can do the same thing, more or less with an iron sledge, albeit with less mobility.
