Hey so im reaching to my yorkie mamas in quest of some answers ,comments or suggestions. My lil man Max is soon to be 1yr old and hes developed some bad habbits while we are staying at my boyfriend's place. My boyfriend has a dog about 2 months younger then max , andwhen we came here he wasnt very well trained as he barks at nearly every noise.

Well long story short is Max has started growling at every noise outside. He isnt like this , he is usually very lazy always sleeping .I mean he is still lazy but plus the growling too much.

Now, he has gained some kind of territorial behavior. Usually by 10pm we call him over to go sleep with us and if someone opens the room door while we in bed, he growls continously at them as if he doesnt recognize anyone.If the other dog jumps on the bed an tries to approach either of us ,he attacks. I mean not trying to hurt the dog just like warning, but still he attacks.

What should i do about the behavior and growling at anything? ive been at my boyfriends for like 2 months , this started about 2 weeks ago
