Hi there - congrats on your new little guy - he will be the light of your life, I guarentee it!!! I like the name Izzy, but that is my granddaughter's female cat's name
short for Isabella - so I think girl when I hear Izzy. Of course, that does not mean it IS a girl name. My favorite boy name is Kipper - if I have another little boy Yorkie, he will be Kipper. Good luck on your name selection!
