hi im new so correct me if i post something wrong lol

i have a dog called mack, he's extremely dominent and he thinks he's dominent of our pack. which im sure you can guess causes problems. he barks ALL THE TIME and follows us round (obv checking that his "babies" are ok) now i just wanted to know how i can get him out of this mind set.

i know a little bit of what ishould be doing but not a huge lot, i never let him in the house until i tell him to, i always go through the doors first, i make him sit and stay for his dinner and i eat before him.

some advice would be nice.

oh, and he's like this because he was my nanna's dog and didnt have any training (he's slightly better than he used to be)
