Easily done, I can give you the names of the areas such as Tisy. Tisy is like Wolf-Central. Any time I've gone to Tisy I see wolves. But now they appear to be absent.
I went into a community server and went to Tisy on the Chernarus map for a full 35 minutes, no wolves. That is very unusual, as I've played DayZ for over 4 years. Any time I go to Tisy, at least 90% of the time I see wolves, but not recently.
I would log into an official server and go to Tisy, but that would take me too long to do and I could always get killed before I get any chance of going there.
Every time I go to Zelenogorsk, I at least hear wolves howling in the distance, but recently there has been nothing.
Another wolf hot spot is Kozlovka, just southeast from Zelenogorsk. About 50% of the time wolves spawn there. I camped out there just recently and saw no wolves.
On my LAN server, I have been teleporting like crazy here and there all over the northern area of the Chernarus map and have seen nothing.
Here is a link to the interactive map if you want to see the wolf spawns: https://dayz.xam.nu/#6146.25;5600.63;4
