Aww ... the poor guy is having some issues
You said you have had him for 3 months .... while you have been caring for him for even longer it sounds like he has been taken out of his previous home and put into different living conditions
Dogs will often "act out" when there is a big shift in their living conditions
They become confused and that can often become either aggressive or timid when this happens
