Hooch wants to eat other dogs

[Ruhkus]

I have an 8 month old dogue de Bordeaux (think turner and hooch) named nala. She is angel in the house loves everyone and everything. However our dail walks are a challenge. She is aggressive towards everyone and everything. This came about after I had to keep her calm for 4 weeks cause of discomfort in he hip. When I took her out again it's like she has been possesed by a devil and it has been like that ever since. My reaction is hat she is just unsure about Things and responds with aggression. But I don't know. Anyone have any ideas or been through the same thing ?
