Dude these jutsu are rigged, especially since they are sort of C rank jutsu, and the giant dog doesn't get bigger by getting struck in the manga i thought, it was jjust a few dogs which were summoned that split apart and grew really quickly then jiriya pwned them.
I create 3 shadow clones and 3 of me use
(Katon:Gouenkyuu)-Fire Style:Great Blazing Fireball
* Type:Attack
* Range:Short-Long
* Chakra cost:20
* Damage Points:40
* Descripton: A bigger and more powerful version of the Grand Fire Ball jutsu that carries the opponet off on contact.
to make a really big fireball, then 1 of me use
(Raiton No Jutsu)-Lightning Technique
* Type
efence/Attack
* Range:Short
* Chakra cost:10
* Damage Points:20
* Descripton: Small static bolts for attack and defence.
to give it an electrical charge which destroys all of your dogs.
