My dog was terrified the first time I played my guitar. It pressed its snout against my strumming hand just to make the "horror" stop. But after a while he didn't even bother anymore. Perhaps he first thought that it was some kind of torture machine but now he is totally relaxed when I play guitar around him.

He's even immune to power chords, so maybe if you keep at it he will get used to it (MAYBE, because I'm not a dog expert lol).

Anyway congratulations on achieving this much. Learning guitar keeps being addictive if you always have the right new stuff to learn, no matter what level guitar player you are.
