I didn't find the book to be very funny. The humour is very much based on puns. Though some of them are clever, I didn't find them to be funny at all. I reckon that kids will likely enjoy the book. There are a lot of jokes that I don't think kids might understand, due to the jokes using puns or words they mightn't understand. However, there's a few dog illustrations on every page, all of which a kid will love. Overall, I didn't like it, but I think a kid might.
I "bought" a copy of this from Amazon.com.au when it was free. These are just my honest thoughts.
