Professional human athletes never skip a proper warmup. That's because research has proven, repeatedly, that preparing your muscles for upcoming physical activity reduces the risk of physical injury. And for them, an injury could impact their wallet with down time.

My Border Collie Duncan solves all 10 of his interactive puzzles within five minutes; it takes me longer than that to fill them with treats! So when CleverPet announced its Kickstarter campaign for the development of a next-generation pet-learning console, I signed right up. Thirteen-year-old Duncan has pretty severe arthritis so I'm constantly searching for low-activity ways to engage him. This eagerly anticipated device features three durable yet sensitive touch pads that interactively light up and are designed to be touched by a dog's nose or paw, triggering food to be dispensed. CleverPet adjusts learning levels based on your dog's performance, which can be monitored through the website and an app-based program.

Four veterinarians from the School of Veterinary Medicine at the University of California, Davis, published a study in the June issue of the Journal of the American Veterinary Medical Association, entitled “Evaluation of recipes of home-prepared maintenance diets for dogs.” I don’t think any WDJ readers will be surprised to hear that their findings were not exactly positive. The study analyzed 200 recipes. Of those, 133 were obtained from 2 veterinary textbooks and 9 pet care books (two of which were also written by veterinarians), and the remaining 67 recipes came from 23 different websites. Of all the recipes analyzed, 129 were written by veterinarians, and 71 by nonvets.

As a canine behavior specialist, I've seen my share of dogs over the years who suffered from separation anxiety. The vast majority of my clients have been able to modify their dog's distress when left alone, and I felt confident in my knowledge of the issue. Then my husband and I adopted a two-year-old Husky-mix from our local shelter, and everything changed.

Several raw feeders contacted me after reading my homemade diet guidelines (“You Can Make It”) in July’s Whole Dog Journal issue. While their diets varied considerably, each had problems that are common with raw diets – but most are easily fixed. For example, many raw diets are high in bone, which provides calcium and phosphorus. Excess calcium can lead to serious orthopedic conditions in large-breed puppies, especially before puberty. High-calcium diets are not dangerous for adult dogs, but calcium binds other minerals, including zinc and iron, so a diet high in bone may lead to other nutritional deficiencies. Too much bone can also cause constipation.

Gertrude Stein might have thought that a rose is a rose is a rose, but with over a hundred species and more than a thousand named cultivars, the genus Rosa has been among the world's most appreciated plants for millennia. And they can be appreciated by dogs, too, with numerous applications for medical, emotional, and behavioral afflictions. Roses grow, with and without thorns, as compact or miniature varieties, trailing vines, climbing plants over 20 feet tall, and impenetrable shrubs. Their flowers range from large to small in white, pink, yellow, orange, and every shade of red. Most roses are native to Asia, while some originated in Europe, Africa, or North America.

Sometimes life-threatening illnesses develop so slowly that no one pays much attention. An older dog who's always thirsty drinks huge quantities of water. He's hungrier than usual and has developed a thin coat and pot belly. He pants all the time, and now his hind legs are losing muscle tone and getting weak. Many owners dismiss these as normal signs of aging, but they are classic symptoms of Cushing's disease, which affects an estimated 100,000 dogs in the U.S. every year.

Cancer. My heart dropped to my stomach. In February 2010 my Border Collie Daisy became one of an estimated six million dogs diagnosed with cancer each year. Chemotherapy. My stomach tumbled to my feet. The diagnosis was scary enough; how could I possibly consider chemotherapy? I had visions of a treatment worse than the disease itself. As it turns out, my preconceptions of chemotherapy were far worse than its reality. Chemo hasn't cured my dog – more on that later – but it's given us more than 18 months (and counting) of joyful, quality time together.

Over the past few months, I've read more than 30 books on homemade diets for dogs. Many offered recipes that were dangerously incomplete; a smaller number provided acceptable guidelines but were confusing, unduly restrictive, overly complicated, or had other issues that made me recommend them only with reservations. A few were good enough to recommend without reservation. This review is about the cream of the crop: three relatively new books (one is a new edition of an older book) whose authors have taken the time to analyze their recipes to ensure that they meet the latest nutritional guidelines established by the National Research Council (NRC).

When someone becomes interested in feeding their dog a homemade diet, I always advise them to read at least one book on the subject before getting started. But which one should you choose? Guidelines run the gamut from diets that have been analyzed to ensure they are complete and balanced, to those that are dangerously inadequate. How do you tell the difference? I decided to check out the homemade diet books that are currently available. Some of them I’d read before, but wanted to take a fresh look at; others were new to me. It’s been an eye-opening experience.

When Ella, a five-year-old Norwich Terrier, first came to live with me a few months ago, she weighed a svelte 10.8 pounds. But within two months her weight had ballooned by almost a full pound, and there was no way you could call her anything but plump. How could this happen? How could I have let my new dog get fat – me, the one who perpetually preaches the benefits of keeping dogs lean? And what the heck was I going to do about it? The answer is that it happened because I’d never owned such a small dog before, and it turned out I was massively overfeeding her, particularly when I counted all the treats she was getting. And I would do whatever it takes to get her back to the weight she should be, and keep her there. Here is what I learned during my struggle to help Ella lose weight.

At some point in our lives, some of us find ourselves living with a difficult dog, one whose behavior challenges our patience, and exhausts our training knowledge – and opens our hearts and eyes to a new, better way of training. This is the story of one such dog and her very knowledgeable dog owner. Together, they reached an entirely new and higher level of dog training skills, thanks to the owner’s life-altering experiences with a reactive dog who wasn’t fit to compete in the career intended for her: Flyball. Flyball is not the sport for everyone. It is a relay team event, which means you have to commit to training and competing with your dog and other dogs and dog owners as a team, and you have to have an appreciation for over-the-top dogs and the resulting cacophony of sounds. In flyball, a team of four dogs race, one after the other, leaping a series of hurdles, throwing their bodies against a spring-loaded box that ejects a tennis ball, snatching the ball, and hurtling their bodies back down the row of jumps to where their next teammates strain to be released for their turns. The fastest team wins.
