Helping Your Pet Lose Weight: A Practical Guide for Dogs and Cats
Firstly, we love and adore ALL pets - including the porky ones! But unfortunately for those extra squishy, ‘more to love’ pets - obesity is no joke, and can genuinely take years off their lives. Pet obesity is one of the most common health problems veterinarians see - and it is far more serious than many people realise.
In fact, studies estimate that around 40–60% of dogs and cats are overweight or obese in developed countries.
While a few extra kilograms may seem harmless (and VERY easy to do!), excess weight can significantly reduce your pet’s quality of life and contribute to long-term health problems.
The good news?
Even small changes can make a big difference. Let’s get into it!
Why maintaining a healthy weight matters
Excess weight places extra strain on your pet’s entire body.
Overweight pets are at increased risk of:
Arthritis and joint pain
Diabetes
Heart disease
Breathing difficulties
Reduced mobility
Lower energy levels
Reduced life expectancy
In some studies, lean dogs have been shown to live up to two years longer than overweight dogs. Two more years with your best mate - worth it, if you ask us!
Step 1: Know your pet’s ideal weight
The number on the scale only tells part of the story.
Veterinarians use Body Condition Scoring (BCS) to assess whether a pet is underweight, ideal, or overweight based on:
Rib coverage
Waist definition
Abdominal tuck
Overall fat distribution
A weight check with your vet is the best place to start, or just swinging by for a weigh-in and seeing our lovely nurses out the front.
Step 2: Measure food accurately
One of the biggest causes of weight gain is accidental overfeeding.
Common mistakes include:
Guessing portion sizes
Free feeding throughout the day
Too many treats (we know this is a hard one)
Multiple family members feeding extra food (the grandparent effect, or perhaps a toddler alliance)
Using a measuring cup or kitchen scale can make a significant difference.
Step 3: Treats count too
Treats often add far more calories than owners realise.
Instead of high-calorie treats, try:
Small portions of carrot
Green beans or peas (trust us on this one)
Commercial low-calorie treats
Using part of your pet’s daily food allowance for rewards
A good rule:
Treats should make up less than 10% of daily calories.
Step 4: Increase exercise gradually
For dogs:
Increase daily walk duration slowly, if they are fit and able
Add extra play sessions
Use enrichment games that encourage movement
For cats:
Puzzle feeders
Food-dispensing toys
Laser or wand play sessions
Creating vertical climbing spaces
Cats especially benefit from short, frequent bursts of activity.
Step 5: Rule out medical causes
Sometimes weight gain is not simply about food intake.
Medical conditions such as:
Arthritis reducing activity
Hormonal disorders
Age-related metabolic changes
can all contribute.
If your pet is gaining weight despite a controlled diet, a veterinary check-up is important.
Weight loss should be gradual
Rapid weight loss can create serious health risks - particularly in cats.
Safe weight loss is usually slow and carefully managed over time.
The takeaway
Helping your pet lose weight is one of the easiest and most effective ways to improve their long-term health and wellbeing.
Better mobility, reduced disease risk, improved quality of life, and often a longer lifespan all start with healthy body condition.
