How long should a healthy weight loss plan take for a dog?

Losing weight too quickly can mean losing muscle mass alongside fat, which is not the goal, whereas a gradual pace gives the body time to lose fat while better preserving muscle.

A longer, steadier timeline is also generally easier to stick to consistently, since smaller weekly calorie deficits are less likely to leave a dog constantly hungry or the owner tempted to give up.

Calculate the total amount to lose in kilograms, then divide by 1 to 2 percent of your dog's current body weight per week to get an estimated range of weeks or months.

For example, a 30kg dog needing to reach 26kg, a 4kg loss, at around 1.5 percent of body weight a week, roughly 0.45kg a week initially, would take around nine weeks, though the weekly amount lost typically slows as weight decreases.

Weigh every two weeks and expect the rate of loss to naturally slow somewhat as your dog approaches target weight, which is normal rather than a sign the plan has stopped working.

Celebrate milestones along the way, such as every kilogram lost, to help maintain motivation over what can be a several month process. A visible record, such as a simple chart kept on the fridge, can make gradual progress feel more tangible than relying only on memory of where the plan first started several months earlier in the whole process, back near the very beginning.
