about a boy who (i think) trips over his dog coming down the stairs in the morning, makes him mad, so he is mean to everyone all day. The book shows how the anger/meanness is spread from person to person. It then show either the next day, or an alternate reaction and how niceness and kindness is spread to everyone. (I think maybe in the negative day it spreads around until it comes back to him and someone is sharp/mean to him) I read this book in my local library at least 19 years ago.
Bit of a long shot, but it might be ‘The Lemonade Trick’ by Scott Corbett.
“The Quarreling Book” by Charlotte Zolotow?
YES! it is the Quarreling Book. Thank you everyone for your help!!
This sounds like The Sorely Trying Day by Russell and Lillian Hoban.
