Speaking up for myself

I dislike confrontation very much. I don't want any uncomfortable feelings to come up and for things to be awkward. I always feel bad to hurt someone Else's feelings and at times this comes at the expense of my own happiness.

I'm having this situation with my landlords dog pouncing on me or my family when we come through the gate to my front door. I'm not a fan of Dogs jumping on me and especially when they are not tiny. I feel that out of respect for their tenants that they should walk their Dog and not let it loose. At one point they told us that if the Dog is in the way we can call them anytime and they will bring her inside, but this still bothers me. I feel that I shouldn't have to call them. They should just be considerate knowing that they are not the only one's living in the house.

It makes me uncomfortable to have to address this with my landlord out of fear that things will be awkward. I have been this way my whole life. I know I have to get over it but not sure where to start. When I'm not able to express myself I either become angry and take it out on my family or myself in the form of binging.

Has anyone overcome a fear of confrontation and how did you do it?
