There's really no point in counter jungling. I average getting my devourer item between 7 and 9 minutes and have it fully stacked by 14 to 16 minutes. She clears too fast for Voli but Voli is a super early game jungler and early game junglers counter Shyvana (Nidalee is the hardest counter, but a good Lee Sin, Evelynn, Elise are extremely good against her). If your score is 2/0/4 at 6 minutes, she's in trouble, because there's really nothing she can do to stop you at that point and the game is getting out of control for her before she's even had a say in it and that's exactly what she doesn't want. Whenever I play Shyvana i always have to gamble that the enemy jungler just simply won't do well when he ganks because there's really nothing I can do to stop him until I hit level 6 and even then I'm just going to be farming a lot.
If you're playing against a decent Shyvana she'll always do the Valkrin super clear, meaning she'll take krugs, raptors, wolves, gromp, back, and then do a full clear.
A cheesy way to get a kill early is to go to her gromp at around 2:30. I always time what time I kill gromp (or krugs depending on the side) before my first back and it's usually 2:50 to 2:58 and then I instantly back, however I'm always REALLY low. If you wait in the blue buff bush at 2:30, wait for me to get low with gromp and rolling thunder and some auto attacks, possibly a flash would kill me instantly for a cheesy first blood. It's never happened to me, but anyone could easily do it and a good shyvana will run exhaust instead of flash so you have to keep that in mind because you are guaranteed to burn her flash or exhaust this way. I really hope that people don't start figuring this out and doing this to me though, probably shouldn't even post this tbh
Another thing is that once Shyvana finishes her 2nd clear she will almost always try to gank top, because she'll be about 3/4s of the exp needed to reach level 6 and she's hoping she can get a quick first blood for level 6. If your top lane is pushed in and she can't gank she'll most likely go for scuttle or try to counter jungle your top side or gank mid. You are very unlikely to see her bot so you can expect her to gank top or mid at around that time. I think it's somewhere around the 5 minute mark.
Don't get tracker's knife. Just buy vision wards, it might be a good idea to hold off on the oracle alteration as well. The most important thing is to hold your E because if you don't hit her with it she'll most likely kill you or your laner. Also never use rolling thunder on Shyvana, it's a waste.
Also if she never ganks, then just gank more. She's gonna want you to try and counter jungle her because you're ultimately wasting your time and not ganking, giving her more breathing room to farm and not worry about you. You'll ultimately lose exp walking to her jungle and back if you just somehow happen to catch her jungle camps uncleared, but most of the time she'll have cleared it long before you get there. To keep it simple, play for the early game as hard as you can because she can't do anything about it. That'll win you the game, unless your ganks aren't successful. I should also point out that you're better off giving your laners the kill especially against Shyvana because she will beat you no matter how fed you are because you're not a damage dealer. If your team gets to the point where they can kill Shyvana in 5 seconds, you won. That's what you want to have happen as Volibear.
I played a Voli jungle game yesterday in which I went 6/0/0 in the early game, ganking every lane and snowballing the fuck out of them. Shyvana barely appeared out of her jungle, but despite my efforts my lanes were still not doing too well. I thought, whatevs we can still win, I'm fed.
