Lox indeed love to roam. They are very easy to breed as they tend to stick together in groups of 2+, so throwing stacks of food equivalent to the amount of lox in the group will almost always guarantee coitus and an increase to the cabinet. It is more practical to build an earthen wall around structures one wants to protect rather than a wall to contain them. Continuous breeding will increase their numbers so that roaming is not an issue. Lox seem to prefer congregating around large rocks, which makes it very handy during "You are being hunted". The only downside is they will denude the area of trees, which is not really a problem because trees are easily replaceable and a lack of trees makes deer & boar hunting much easier. Hunting deer (or any creature) on the back of a lox can be a lot of fun. When I hunt on loxback, I will dismount but stay standing on the lox' back and pick off prey with my bow, or deathsquitos with my knife.

Wolves on the other hand, tend not to roam far from the place they are commanded to stay. So placing packs around ones HQ, especially in areas deer and or boar spawn will keep them fed and increase their numbers. Offspring will move 50-100 metres away from the pack just before they mature to adults. Large packs 6-10 placed 50-100 metres away from each other will help considerably during invasions (I've seen 2, 2 star wolves take down fuling beserkers in 2-3 strikes, likewise trolls, their main weakness is against the poison from "A foul smell from the swamp".
