Not all big dogs are scary
That's prejudice. You shouldn't be afraid of every dog that's bigger than you just because a traumatic experience in the past. I wish I could explain to you how that was a one time occurrence and that it won't happen again. Plus, Mommy and Daddy were there to protect you that time and we will be the next time too.
On the other hand, it's good to be cautious and aware of your surroundings. Also, it's adorable when you put your tail down and approach with caution. I like that you're a little timid.
I SEE THE SQUIRREL TOO. IT'S OKAY.
I'm sorry I yelled at you
Come here little dude; have a seat. Look, you are the best little schmedium guard dog that we could ever want and I love that you take your job seriously. Here's the thing, I'm just not that worried about leaves blowing in the wind, the flag flapping in the window, or the little kids across the street.
One more thing, I'm sorry that I get mad when you drop your toys by my feet and growl while I am working because you want to play. It's awesome that you like to play so much and it would be even more awesome if I didn't have to work and could just play all day. We're both REALLY lucky that I get to work from home sometimes and spend time with you but you have to chill and let me do my thing. Because if I get fired, it's back to Cheerios and generic Peanut Butter, Kiddo.
