Skill runs hello intent regardless of utterance spoken

Hello. I’ve made the first alexa skill, but I noticed that when issuing the command “Alexa tell code academy to say dog” it executes the HelloIntent function.

dog is not in my sample utterance list for the HelloIntent, so I’m confused as to why this is happening.

I’m a total noob. Sorry if this is a silly question.

Please help.

Thank You.
