Good things come in threes. For STEM Friday and the Year of the Dog, we have the third National Geographic Kids book about dogs published this year,  Dog Science Unleashed: Fun Activities To Do With Your Canine Companion by Jodi Wheeler-Toppen and with photographs by Matthew Rakola. (See our previous review of the first two.)

Building on common activities that dog owners already do with their pets like bathing them, playing with them and feeding them, Jodi Wheeler-Toppen has come up with over 20 science explorations to discover more about dog biology and behavior. For example, you can learn more about what colors dogs see by hiding different colored balls in a grassy lawn and watching how easy it is for the dog to find them. Another activity involves making dog treats for your dog.

Safety is first with all these activities. The author remind kids to watch for signs the dog is upset or uncomfortable, and to quit the activity if the dog is unhappy. Also, make sure the dog has access to water and plan lots of breaks even if the dog is enjoying himself.

In addition to the activities, the book is full of cool scientific information. Did you know that dogs have a special vomeronasal organ (also called Jacobson's organ) in their noses that allows them to smell special pheromones?

As to be expected from National Geographic, the photographs are fantastic. The photographer followed kids and their super-photogenic dogs as they tried out the activities. The results are inspiring.

The bottom line is that Dog Science Unleashed is a great choice for dog lovers, as well as budding zoologists and veterinarians.

Delving Deeper:

More about the Vomeronasal Organ

Recently scientists and veterinarians have been able to synthesize some of the pheromones (scents used by animals to communicate with one another) detected by this special organ in a dog's nose. For example, pheromones may be added to puppy potty training pads to help attract the puppy to them. Other pheromones, called "dog appeasing pheromones," may help calm dogs down. You can now find products at pet supply stores in the form of sprays, wipes, and even special collars. Think of ways you can learn more about dog pheromones.

Last year members of our 4-H club designed simple mazes and let our pet mice try them out. Because of that past experience, we were totally in awe and inspired when we saw this mouse in action.

I have two comments. First, this is a special mouse. We found each of our mice had distinct personalities. For example, our present mouse, Squiggle, would be way too shy to do this. We did have a mouse named Spot, however, who would have loved to have this sort of stimulation.

Second, note the black dots about the course. I suspect the mouse has left droppings because it has run the course before. Mice have a keen sense of smell, and by leaving the droppings it was probably able to get cues from them. I know wild mice have been shown to create piles of debris to act as trail markers.

Check our post on pet mice for more information about activities you can do with a pet mouse.

Thanks to our friends, the Millers, for pointing out this amazing mouse video!

For those of you who have doing the cat science projects, try adding coffee to the smells experiment. I accidentally dropped a few coffee beans of the floor yesterday and my cat went wild for them. See how your cat reacts to coffee and tea and let me know. By the way, chocolate can make dogs and cats very sick, so avoid letting your animals eat any.
