why don't dogs watch tv ?, page-5

...I mean my dog seems fairly intelligent ,she knows all the basics :- sit , stay ,no etc...does a few tricks ,is very observant, and likes nothing more than a good feed , a good scratch and a good crap...all of which I can relate to ...
...but when it comes to T.V. she just doesn't get it...for instance , if a dog or cat or whatever is barking and running around on the tv , she'll run past it and stick her boofhead out the window looking for the noise...and I say 'IT'S ON THE GODDAM TV for chrissake !' , but she doesn't listen...
