trying to get a function to recognize differece between bold font and regular font

I would like to get an if function that will display the bold item and need help writing it could someone help me out

here is a basic example of what I am looking for, I want the bolded text in column B to continue on each line item in column A until the next bolded text in column B

A B
Dog Dog
Dog 1.00
Dog 2.00
Dog 3.00
Cat Cat
Cat 1.00
Cat 2.00

let me know if you would be able to help me create this

looking for the bold application that one won't work exactly how I need it to

Function IfBold(Cell)
If Cell.Font.Bold = True Then
IfBold = 1
Else
IfBold = 0
End If
End Function

I was trying to make a function that would at least separate the bold from the not bold and my function isn't working could someone help me out with it?

still havening problems so when I put this function into excel and nothing. is there something I'm missing like how to enable these functions or something. I am a beginner at this so I probably need a step by step
