when i jungle with warwick i like to start off with the long sword and a health pot with this build its really easy to start a fast jungle instead of going with the cloth armor and the 5 health pots.Also he is a very strong mid and late game champ.And has very good map and dragon control when jungleing with warwick he is basically the best jungler in my opinion because he can be a a tank and fast dmg champion when needed to be one such as when your teams is down in kills fairly a lot go with a malady and you should be able to get the kills even in matter on minutes.

i personally go with the smite for obvious reasons I also like to carry the ghost so when i gank a lane at lvl 6 i can easily poke a champion down one bye one and pick up the kill for are team and getting to have a better late game.

Warwick is a very good counter jungler if you have a support on your team like a sona or soraka and get them to carry a clairvoyance with them to pin point out locations on the map and be ready if the enemy jungler is coming toward your camps beware of nunu and trundle because he is a very good counter jungler and basically hard to stop with the ice blast which slows and takes a ton of damage at the first few lvls of the game

For map awareness I suggest you carry sightwards to prevent ganks from happening bye laying the in the rivers beside the lanes. But if the enemy jungler does this I suggest you carry a oracles to find the wards and destroy them and they will no longer know where you are and give your team a advantage.Also lay down the wards where the baron and dragon is so you can tell when they decide to do these.

I suggest get your team mates to help you with the blue buff golem and the wolves when the game starts

my jungle route with warwick is starting at blue and sweeping down the map camp after camp blue buff, wolves, wraiths, red buff, and the double golems at the map for a quick lvl 3-4 between 5 minutes into the game.Ganking do not gank with warwick unless you have the red buff or you or lvl 6 and have your ultimate any other time your gank will be almost failure
