I've attempted several recordings of my dogs and tried uploading them to youtube and most of those videos took like 2 weeks to finally work!
I got my two yorkies Cookie & Angel and my Maltese Lola to all sit in front of me to do their tricks. Poor Lola only learned to sit after about 18+ months of training! lol Cookie does sit,stay,crawl, give me paw. Angel sits,down,Bang ! Bang! (plays dead) lol even though he chooses to die slowly lol as you will see on this video
If you can't see it ,search for My 2 yorkies and Maltese tricks.
