What a cutie you have.
It's easiest to post a video from You tube. You load your video to You Tube, then click there to share and copy the URL they provide. Then come back here and start a thread in the Video and Pictures section. Then click on the little icon on the toolbar above your text box that looks like a film strip. A pop up box will come up. Paste the URL from You Tube in that pop up box and then accept it. Then add your text to your message box and submit. Voila Video posted with a picture link.
