Don't stress it... your teacher will see how embarrassed & nervous you are about the situation... we have to be careful w/our dog, too... anything paper-wise or the boy's toys that have plastic, he'll shred or chew... even tho he has chew toys... he knows it's wrong, too, but doesn't control himself.... it's like he saw me the last time & right away did a cower type thing with his head hunkering down like, "uh, oh".. when he's chewing on his toys he doesn't do that when he sees me look at him... so he's not stupid, he knows he shouldn't be chewing on certain things... when he was a puppy, four months old when we got him, he had chewed some of the wood under my kitchen chair & also chewed a plastic connector end for my printer cord.. such a Marley & Me & a Hachi dog... & worse... when my boys play with their Lego sets, or Hero Factory sets, I help them keep an eye on the area to make sure they don't drop something on the floor... he had chewed up their new firemen truck sets & we realized then they couldn't turn their back on him w/their toys out... soo, we usually keep the dog in the bedroom while they play out in the living room (more space) w/their toys =) .... it happens..
Your mom can just write the note & explain what happened... it'll take the pressure off of you... she can request the price of the replacement book... don't feel bad, it's happened to our stuff, too! =) Accidents do happen when you're not use to having a dog around.. now you know & will keep it up & out of the way... or keep your door closed & make sure you're watching that the dog doesn't sneak into your room when you open up.. =) ~ours is a little Maltese Bichon... about 10 lbs... =)
Best to you & your school year! =)
added to your extra details: Sure!
Just start off saying, "Mr. Teacher, I am very sorry to tell you this."
Then start explaining to him what you said to us.
Say it how it happened, "I left my room for a bit & when I came back, my dog was chewing on my English book. Here is a note from my mom."
Hand him the note. Your mom should be sending in a note advising your teacher she is aware of the situation & is prepared to pay the replacement cost of your English book.
She could write something like, "Mr. Teacher, please except our apologies for the accidental damage to (your name like: Bob) Bob's English book by our dog. Please let me know what the replacement cost is for the book. Thank you for your understanding. Sincerely, Mrs. ____________."
Your mom will have to write it, sign it, & let him know she is aware & prepared to help you take responsibility.
He'll understand. This stuff does happen. Since your parents are aware & ready to correct the accident, he shouldn't be mad. While he is reading the note, get the book out & hand it to him after he's done. You can then reiterate that you are sorry. Just a simple, "sorry" as you hand the book to him. =)
Have a good day! Don't stress, it doesn't help. Just put it out of your mind til the time but keep your reflective sincere apologies toward the situation when you need to bring it up again. =)
