Inuzuka- When starting out, have the dog follow you around. And as your Dog gains expierience, have it grow in Size.
Tsuuga-Using the Arrow Keys to Control your self, and WASD for the dog, this will allow both of them to strike at different angles and times making it harder to be predicted.
Gatsuuga-This would work the same way as Tsuuga, but they could combine their Tai, and do more Damage.
Shikakyu no Jutsu-Beast Form. This would put you on all fours, doubling your speed, This would increase your Tai, and your sense of smell. This would allow tracking if the opponent is Pissed on, and possibly Tsuuga/Gatsuuga homing. Would last 30 Seconds. Having such a heightened sense of smell, the smallest things can paralyze him. So have it where if you eat enough Ramen, a 'Fart' Verb comes up (xD), and if you drink enough Sake, abd 'Burp' Verb will come up, and if used around a Inuzuka in Shikakyu, they will become paralyzed for 20 seconds
Juujin Bunshin no Jutsu-This will make the Dog look like yourself, even having the same name.
Sotoro- This form is combined with Juujin Bunshin, to create a huge two-headed wolf. In this form, Gatsuuga is replaced with Gouroga, Increasing damage immensely. Also, a 5% chance to cut the opponent into two, ending in a one hit kill.
Dog Piss(?)- This move would allow your dog to piss on the opponent, and in doing this, While in Shikakyu, you are able to find the opponent no matter what, even being able to see the jutsus it is performing. This also makes Gatsuuga and Gouroga homing, being they both have a heightened sense of smell in the forms.
