SlimDoggy’s first product is a mobile app like a “Nike + or RunKeeper for dogs” and is based on our experience with Jack- a Yellow Lab that we rescued in August 2011. He was 105 lbs. and on both Prozac (for anxiety & hyperactivity) and Rimadyl. Jack was ‘unadoptable’- he was in the shelter for over a year before we took a chance on him. We knew we had to change his lifestyle and his weight to get him into a good, healthy state. Using scientific research and guidance from our orthopedic vet, we created algorithms (using an excel spreadsheet) to figure out portion sizes and calorie targets based on his daily activity. Within 3 months, Jack was down to 85 lbs, off of both medications, and is now a happy and healthy dog– his behavioral problems disappeared as fast as his excess weight!

Little did we know that there are a lot of dogs like Jack: there are 41 million overweight/obese dogs in the US and the incremental cost in vet/medicine bills for this is an estimated $6-8 billion annually. Upon learning these startling statistics, we decided to share our work and create an iPhone App (Android version coming soon) and attack the dog obesity problem head on. In addition, we are building a set of tools (apps and informational) that will help educate pet owners on topics related to their pet’s health and fitness.

Not only can we help those overweight dogs and their owners, but in the process, we donate a portion of our ongoing revenue to dog rescue organizations that so badly need the help. SlimDoggy has already donated $300 to San Diego based Labradors and Friends Rescue ( ) and is committed to addressing both the dog obesity problem and the dog abandonment problem that we have in the US.

The SlimDoggy App contains a calorie database of about 2,000 dog foods and allows the tracking of the dog’s activity each day. You can input the amount of food you feed them each day and their activity levels and SlimDoggy tells you automatically whether you are overfeeding or underfeeding. You never again have to guess how much to feed your dog!

  1. I don’t have an iphone or any phone that would support your ap, but would love to have access to your program. Do I have any other options?

  2. What a cool little app and I love the story. I’m on my own slim down for Spring. Thanks for sharing.

    • Thanks – glad you liked it. Spread the word to your friends. We are on a mission to fight pet obesity!

  3. Hi, Just purchased and started using your app yesterday. I was thinking ahead and wondered how soon before Bandi would lose one pound if we keep her within the calorie count recommended in the app for her weight. Must Bandi eat 3200 less calories (or burn 3200 more calories)in order to lose one pound?
    Thank you and I’m looking forward to your response 🙂

    • Hi Gail- thanks for trying the App. Yes, Bandi will need to burn 3500 more calories than eaten in order to lose a lb. So that will take some time, which is OK. This is not Biggest Loser and we want our dogs to lose weight gradually and safely. We are adding some new features in future releases, one of which will provide an “ETA” to the desired weight loss. If you send us an email with the key data for Bandi (age, current weight, desired weight, activity type and duration, we will send you back an ETA and some other suggestions. Info at slimdoggy dot com.

      Here are some tips on using the app:

      – Make sure to account for all the food you give Bandi including treats.
      – If you give Bandi any human food scraps, create a new “Custom” food with say, 100 calories per serving. Then add this on the days you server the human food and adjust by increasing or decreasing the amount in the app. So if you gave Bandi about 50 calories of human food- you would enter 1/2 a serving into the app
      – The Calories burned estimate is based on Bandi’s desired (target) weight. If you feed that much you will experience a very slow (and safe) weight loss. Our vet advisers recommend that you can feed 75-85% of that value to speed up the weight loss. So if Bandi was burning about 1000 calories per day, you could feed her 750-850 to accelerate the weight loss (and still be safe) and once she reached the desired weight, you could increase her back to 1000 per day.
      – Remember that the calories amounts are estimates only and based on the dog’s weight, age, and activity levels that you input. Some dog’s will actually burn more than we estimate and some will burn less depending on a myriad of factors (just like humans!).
      – Make sure you weigh often and adjust your feedings accordingly.

      Hope this helps!

      • Thank you for your quick and very informative reply. I am so glad that you shared how it is perfectly okay to feed Bandi a bit less to speed up the weight reduction. I will send you Bandi’s details at the e-mail address you provided so you can give us the ETA to look forward to. You have been more helpful that I anticipated and I appreciate it so much!

  4. Probably not something I would use (since I am mostly free of technology like smart phones- my phone is very, very dumb). But I think it is still a great idea and probably very useful for a lot of people. I can see it being really great for people like runners who take their dogs along while training, who need to be really careful to feed enough to maintain weight.

  5. Hi! I recently purchased the app for my iPod Touch and have been having trouble figuring out how to use it for one of my pups. I feed her a combination of Wellness Core Reduced Fat and Original formula food. Some days I mix in the canned food (also Wellness Core). But I can’t find a way to enter the combination. Please help! She’s at a healthy weight, but no matter how I enter her food, it looks like I’m either over- or under-feeding her.

    • Hi Sue- we just sent you an email with details on how to do this. It’s pretty simple– most of our users feed their dogs some dry, canned and several different types of treats. Let us know if you have more questions.

  6. That’s fascinating and amazing that Jack’s behavior problems disappeared with his excess weight and that he is now off of medication! Do you think the problems had to do with the food he was on or that he was overweight?

    • He was in the shelter for over a year. He’s a big active Lab. To be honest, I think they fed him to shut him up. He didn’t get exercised like he needs and his anxiety just grew and grew until they put him on Prozac. When we rescued him, the first thing we did was get him on a good diet and start walking him everyday – within a week he was running a couple of times a week and within a month, he was running 3-4 days a week for 30+ minutes The exercise completely changed his personality – along with being in a home with some rules and good training ;). He was off the Prozac at the end of that first month and down 20 lbs after 3 months. He’s a different dog. I can tell when he hasn’t gotten enough exercise, he just gets antsy, so we go for a walk. He’s 10 – almost 11, (we think) but he’s a Lab…who spent over a year locked up in a shelter…he still has a lot of excess energy to drain! So, to answer your questions, I think it was a combination – his behavior problems were certainly brought on by being locked up with no exercise, and his digestive problems are probably also due to the stress of that situation and the quality of food he received.
