What’s New in the SlimDoggy App – Weight Change ETA

We wrote recently about some of the new features in the SlimDoggy app.  Today we will focus on what we call the Weight Change ETA feature, which provides a time estimate for how long it will take your dog to reach their target weight.

Weight change scenarios

Whether your dog needs to lose or gain weight, a safe and healthy weight change will take time. We now provide estimates on how long (ETA) it will take your dog to reach their target weight  based on three feeding scenarios.  Remember that you should consult with your vet before making a change to your dog’s exercise or feeding regimens!

1- Conservative Approach- Target Weight Kcals: Feeding your dog the calories they would require if they were already at their target weight.  For dogs who are losing weight, this value will be lower than their current body weight calorie requirement, thus you will be feeding your dog less than they are burning and they will lose weight.  The reverse holds true for dogs needing to gain weight.  This is the slowest and most conservative of the three scenarios and thus, it can take a long time to reach your dog’s goal.

2- Moderate Approach- Target Weight Kcals +/- 15%: Feeding your dog 15% less (for weight loss) or more (for weight gain) than what they would burn at their target weight.

3- Aggressive Approach- Target Weight Kcals +/- 25%: Feeding your dog 25% less (for weight loss) or more (for weight gain)  than what they would burn at their target weight.  This is the most aggressive of the three scenarios and according or our veterinarian advisers, you should view this as the maximum (for weight gain) or minimum (for weight loss)  to feed your dog.


The Logic

We wrote a whole series on the calorie requirements for dogs; you can read part one of that here.

For a dog to lose weight, they must burn more kcals than they consume.  Similarly, for a dog to gain weight, they must consume more kcals than they burn.  In order to lose a single pound, 3500 more calories must be burned than consumed and vice versa in order to gain a single pound.  Just like humans, right?

Our app calculates a Weight Change ETA in weeks for each of the three scenarios using your dogs current and target weight and average exercise activity levels as inputs. Of course, this calculation assumes that you comply with your feeding and exercise targets and that your dog’s metabolism is ‘normal’.  Want to update the ETA?  Simply enter in your dog’s current weight and activity level (if changed) and we will recalculate the ETA for you.

Other Considerations

1- If your dog is in weight change mode, we recommend that you weigh them often (every 2 weeks) and update their current weight in the App.  This will result in an updated ETA plus you can tweak your dog’s activities/feedings according to their progress.

2- Don’t forget to account for treats and table scraps.  Unaccounted for, these alone can sabotage a weight loss plan.

3- If your dog needs to gain weight, you still need to track activity and feedings.  And slow and steady is the best way from them to gain weight as they will respond with muscle gains instead of fat gains.

4- Get your vet’s approval before embarking on a significant weight change plan for your dog.
