Aggressive Dog if woken up help

[pinky]

First of all..... how old is the dog? The dog may be goin deaf or senile. Best to get the dog to a vet and have it checked. If not the dog may get to the point of biteing. I'm sure you don't want that. If the dog is going deaf..... now is the time to sorta retrain him/her to get use to you stamping on the floor when you enter a room where the dog is. I have had dogs that went deaf and that's what I have had to do. As for if the dog is going senile..... theres not alot you can do and there is only 1 road you will be travellin down . I hope this helps.
