My dog can be a little aggressive

[*LabLoverKEB*]

Saying 'oh it's okay, it's okay' is not the best way to handle his aggressiveness... he is then thinking 'oh, it's OK to bark and snap like this'. You need to possible keep Max on a leash under control when you have company, and correct him when he does bark/snap by a quick snap of the leash, and then reward him immediately when he stops the unwanted behavior. Use treats, and noise that gets his attention (squeaker, clicker, etc) and praise, praise praise.
Good luck!

i have three chihuahuas myself and they all bark when some comes in the door that is not us....but what i do is use a spray bottle and they stop immdediately after i tell them to be quiet or if i walk over to the spray bottle....they usually do good if you welcome in the door or step out then come back in with them....well hope to hear of the progress
