Ya i read my dog book when i am training my dog too. In one of our exercises he has to lay down next to me for 30 min and not move...so it gives me a perfect opportunity to read....though sadly the other day, when i left him alone with the book on the floor, he started ripping it to shreds. I think its because i was giving the book more attention then him.
How old is your puppy now?
If he's very young, a 30 minute down-stay is totally unreasonable, sorry.
Your job as his guardian is to set him up to succeed, with realistic goals that he can actually manage.
And--dogs just aren't humans and don't think in spiteful ways as you're implying.
He tore the book up not because he was jealous of the attention you had paid to it, but because you left him unsupervised and shredding paper is FUN.
Dogs do what feels fun to them and satisfies needs for them, period.
Use that to direct him to behaviors you want and phase out behaviors you don't.
