Boys love dogs. That's why they call dogs "man's" best friends, right? Not "woman's" or "person's" best friends. When we were in Florida, Isaac mentioned often that he missed his daddy and Max, our dog. Max is an old mutt with a great disposition who has been sadly neglected during the last five years. But Isaac loves him.
Typically if a book has a dog on the cover you can assume that it is going to be sad. A colleague and I were sharing war stories the other day and she mentioned her group of girls that love stories that make them cry. She tells them to look for books with dogs on the front.
The Stray Dog by Marc Simont comes close to following this pattern, but stops just short of sniffling, which is why it makes the cut for this post. It is a great pet story and, while it is very sweet, it is not so gushy that boys can't enjoy it.
Isaac doesn't love this book, but he does like it. If you are thinking about getting a dog or just looking for a book to satisfy an interest, this is a good choice. However, if you are trying to squash you boy's pleading entreaties for a puppy, stay away. This book may weaken your defenses.
