I've got a little problem with Ahru : he kills me on sight

When i first spoke to him, next to the gates, he was all nice and happy, but now when i come to see him in his study, almost as soon as he see me he change back into human form and start throwing thunder on my character. If I am fast enough, i can speak to him while he his still in his animal form, and he is friendly enough, but as soon as the dialog end he goes berserk.
I stole from a lot of people but i never got caught, and I never stole from him in the first place. The only friendly npc i ever killed was a rabbit. I don't have any problem with any other npc, just Ahru.

[EDIT] He doesn't attack Madora if I sent her alone, so i can still trade with him, but i can't speak about quests since he attack my PC
