Sup, i goin to show u guide and build for a jungle udyr which can tank and do damage. On the stat is said his only got 164 attack but if u add 2% of ur health to attack damage( Atma's impaler) u will get around 200-300 attack damage. As i think tiger udyr is one of the fastest jungler or one of the most fastest jungler.

First start at blue buff but you should alway get ur mid to leash for you as it is alot easily to jungle and u dont have to use any hp pot and still be fine killing the blue with our more then 2 bar hp lost. then go to wolf, you should keep changing move for lifesteal and attack damage and speed, since you got blue u dont have to care about blue. after that go to golem or you can go to wraith, by the time u finish golem/wraith ur smite cd should be 10 second or less. then go and get red buff so you can gank easily with red buff slow, Finally go to Wraith. if u still have half bar hp or more go gank bot or mid, if cant go back and buy the rest of the item.

My mark is all armor penetration and the other are all attack damage rune which allow u to jungle fast. As you see at the top i start of with tiger first so you already have attack speed and more damage.

AS masteries i got 24/6/0. is allow me to do more damage and finish jungling faster. then u got 6 def and 6 magic resist.

At the start u get a cloth armor and 5 hp pot for jungling. You should be able to finish the whole jungle with 5 hp pots. then buy a boots and a long sword for gank or go bak to jungle. after tat keep farming up until u can get a wriggle's lantern go get dragon. u should be able to solo it. after tat get ur Mercury's treads and after that get ur warmog or trinity force (if you are doing good then get a trinity or get a warmog if u die to easily). if u got ur trinity first then now get ur warmog next or eles u want to do more damage get ur atma. After tat, get a GA or other tanky item u want but mainly a GA will be good.

Smite - Because you need to smite things.

Flash - Good for escaping as there a chance ppl gank u while ur jungling. Also good for running away by flashing through wall. Flash is also good for ganking, as you can flash toward them to land a stun with bear giving nearly a 80% dead.

This build should let you have a lot of fun ganking, jungling and tanking. It's always been my favorite way to Play Udyr. so I hope you enjoy it as much as I do.
