Boy this YouTube stuff is such a time drain but there are some whopper nuggets out there. There are a lot of bad videos too. We spare no expense in filtering out the bad and bring you stuff you may not see everyday. First up is the ability to put one's dog to sleep on command. Weird for sure.
Second - the obligatory 'play dead' trick but with a human finger 'gun.'
Finally, teaching your dog to close drawers and doors. I think this may be in Swedish.
