Solihull Dog Training Club

Buddy has just stood or sat in front of the TV for almost an hour, watching,
pets Wild at Heart.
He normally barks at animals on the TV, but tonight he cried occasionally turning and looking at me, when he cried. I have been considering for some time if I should have another dog and trying to look at the pro's & cons of this.
I would appreciate opinions, on- One dog or Two ???
