I can’t really tell what is happening in the initial code but did you declare myDog 3 times? You also have 2 closing brackets } at the end that don’t match with anything.
If you are not passing the tests, please copy and paste all your code again from the editor.
When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.
You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.
See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).
