Student Project Debugging Help

Hello Everyone,
I can’t figure out why this student’s for loop isn’t running. Can anyone take a look and see how to make this work? Thanks in advance: https://studio.code.org/projects/applab/b5PfhFkqy6I762w5KhIn_lZqRbTXx1dl2I4mTZxRjuk

dogSize variable is not being iterated through due to i < dogSize to fix this simply compare it to a number instead by using .length your updated statement would look like this i < dogSize.length
