Depends what level your wolf is.Make sure you give him a crest that gives him holy edge.
It gives a better attack.Heal whenever your health is half. soul comet is also a good tactic.Also a creast with hail break or beak or whatever it is called.

ps: it's been a while since i fought Phillipe.

When i fought Phillipe i just atacked him non stop with hard hit and soule comet then when
Blankas hp got low I yousd heling plants for his hp and sp.

Use a item so phillipe [the wolf] gets only one turn trust me best method to beat him plus
u get health while doing so.
