How We Did It…

angelapp2The SlimDoggy App was created with our yellow Lab Jack as the initial ‘case study’, to obvious great success.  That said, we relied on industry leading research studies and some amazing people to make this project a reality.

We did extensive research and consulted with several veterinarians in order to refine our methodologies and make sure that our approaches are sound.  We researched and collected, by hand, food calories and ingredient lists for almost 2,000 dog foods and treats to compile the most extensive dog food database currently available with ingredients and comparison data so that you can really examine what you are feeding your dog.

Primary Research Source

Many of our calculation methodologies are based on the The Waltham Centre  research as presented in their seminal Paper: Waltham Centre for Pet Nutrition (1999), Canine Life Stages and Lifestyles, The Waltham Course on Dog and Cat Nutrition.

According to the Waltham baseline calculations, the daily calorie requirement of a dog depends on its weight and activity level as shown below.

Dog activity Level Estimated Daily Calorie Requirement

90 x (weight)0.75


110 x (weight)0.75


125 x (weight)0.75

Highly Active

175 x (weight)0.75

We utilized and enhanced the Waltham baseline formulas to be more practical to use and to account for more precise exercise times.

Veterinarian Support

We would not have been able to complete this work without the help of several veterinarian and veterinarian paraprofessionals.

In particular, world renowned orthopedic specialist  Dr. Kenneth Bruecker DVM, MS, Diplomate ACVS, Board Certified Surgeon,  provided guidance and advice on our methodologies and overall support of our concept; Pamela Dilley, RVT,  CCRA, provided encouragement and ideas on both our App and canine fitness and rehabilitation science and techniques; and Dr Michelle Rose Internal Medicine, who’s simple MER calculator was used for initial calibrations and testing. Each of  the aforementioned practice at the VMSG in Ventura California.

Dr. Ken Coscarelli, DVM, of Conejo Valley Vets, Thousand Oaks, CA also provided valuable advice and encouragement  on how to improve our App.

We will be adding more data and expanding the App and our features in the future. If you have any questions or thoughts on how to improve or expand on our App we welcome them in the comments section below.

  1. Just hopping by and saw your post. What a wonderful app. It’s great you have put so much of your time and energy into making sure it’s perfect. So many people make apps that look beautiful but lack substance. Good luck to you and happy Saturday!

    • Thanks for the feedback Carrie Ann, we appreciate it. Tell your friends!

  2. Hi there! Do you have an app for android as well?

    • Working on the Android app. We will let you know when it is ready for release!

  3. Your app is just not working for Giant Breeds. If I fed my dog as much food as the app says to he would be grossly over weight. He currently gets roughly 2600 calories per day. He’s a 110 lb Newf puppy that is fairly active. Your app says he needs over 4000 caps. Granted I’m sure he would be thrilled to get an extra meal, but I suspect that would be counter productive.

  4. The calories suggested by the app seem too high for my dog when compared to other recommendations. I did my own calculation using the formula posted above and – I could be wrong – but to me it seems like the app is doing the calculation using the dog’s weight in lb when it should be using the dog’s weight in kg. I only came to this conclusion after doing the calculation myself with my dog’s weight in each unit. When I used lb I calculated a value extremely close to the one suggested by the app. However, when I used my dog’s weight in kg I got a value similar to the caloric recommendations I’ve gotten from other sources. Is it possible that this mistake is programmed into the app? If not, details should be provided on the formula the app uses to calculate MER so users can be sure of the math and science behind it? I had been using and enjoying this app for months, but now I am starting to question its accuracy.

    • Thanks for the note Michael. As we explained via email, your dog is a puppy and thus, their daily calorie requirements are at least 2 times that of an adult dog.
