Take it from someone raised with English Springers. They are NOT guard dogs. They might bark a little but it's only to welcome the stranger with a mask and gun into the home. They love to be around anything with a heartbeat.
A good lawyer might be able to defend Guido from your presumption that he was responsible for all the torn papers and stuff. If you didn't see him in the act he will claim its "circumstantial" evidence. Now that's good but only if there is no logical explanation otherwise. So Guido and his counsel will argue that he was playing with another dog who did the deed. A judge will instruct the jury that if there are two equally explainable tales as to the criminal act and one points to Guido's guilt while the other points to his innocence then you must find the innocent explanation-and Guido is not guilty.
