Mariko and Lizzie are able to have some fun, making maple sugar candy when they aren't playing with dogs! There are also good details about how maple syrup is made, and anyone who has read the Little House on the Prairie books will be glad to have instructions on how to make the candy.
The Puppy Place books include a little bit of information about the breed at the end of the book, and since there are quite a number of these books (as well as a very helpful nonfiction guide), the author mentions the others breeds that are inclined to be service dogs, including Honey, Shadow, Sweetie and Teddy. Such a long series is great for emergent readers who like to read shorter books but go through a lot of them! This author also has a Kitty Corner series for readers who prefer their main characters to be feline!
