A pet owner’s guide to understanding and preventing dog obesity

Last updated on

Dog obesity is becoming an increasingly common pet health issue in Australia. According to local studies, almost half of Australian dogs are now classified as overweight or obese.

While some cases of weight gain can be attributed to underlying medical conditions, the majority are the result of environmental and behavioural factors—particularly overfeeding and a lack of adequate exercise.

One of the most overlooked contributors to chronic disease in dogs is excess weight. What often starts as an innocent treat here and there or giving in to “puppy dog eyes” can quickly add up—literally.

Pet owners don’t realise that they could actually be harming their pets by spoiling them.

Over time, these extra kilos place added strain on joints, organs, and metabolic functions, particularly in senior pets. Maintaining a healthy weight not only improves a dog’s quality of life, but is also proven to increase lifespan and reduce the risk of pain-related issues like arthritis.

Veterinary experts consistently emphasise that weight management is one of the most effective preventative healthcare measures pet owners can take.

Fortunately, it’s never too late to make small changes that can have a life-changing impact on your pet’s wellbeing.

Signs of dog obesity

Recognising pet obesity in dogs isn’t always straightforward—especially for owners who see their pet every day. Subtle weight gain can go unnoticed, and many pet parents unknowingly normalise a heavier body type.

Here are some common signs that your dog may be overweight:

  • Difficulty walking or a reluctance to exercise
  • Heavy breathing after minimal activity
  • Lethargy or reduced interest in play
  • Struggling to groom themselves properly
  • Frequent joint stiffness or limping, especially after rest

Use the Body Condition Score (BCS) chart developed by the Association for Pet Obesity Prevention to assess your pet’s shape more accurately:

7 ways to help your dog maintain a healthy weight

Managing your dog’s weight involves more than just diet and exercise—it’s about creating sustainable habits and making thoughtful decisions based on their breed, age, activity level, and overall health.

1. Break up meals into smaller portions

Instead of cutting food drastically, spread meals throughout the day to prevent hunger spikes and begging.

2. Choose high-protein, low-fat diets

Switching to a healthier formula can make a significant difference. Always consult your vet before making any dietary changes.

3. Encourage more movement

You don’t need to run marathons—regular walks, play-based dog training, fetch sessions, or interactive toys can keep your dog active and stimulated.

4. Use puzzle bowls or treat dispensers

These slow down mealtime and provide mental enrichment, reducing overeating and boredom-related snacking.

5. Visit your vet if weight gain is unexplained

If your dog’s food intake hasn’t increased but they’ve still gained weight, there may be an underlying health condition like hypothyroidism or Cushing’s disease. Some dogs also develop polyphagia, a constant feeling of hunger due to hormonal imbalances.

6. Add fibre to their diet

Low-calorie fillers like carrots or cooked pumpkin can help your dog feel full without adding unnecessary energy.

7. Minimise table scraps

During family meals, place your dog in another room with a chew toy or treat-dispensing puzzle to reduce begging and accidental overfeeding.

Final thoughts: Why dog weight matters

Obesity in dogs is not just a cosmetic issue—it’s a medical one. From increased risks of diabetes, arthritis, heart disease, and reduced mobility, the long-term health implications are serious.

By being proactive, pet owners can reduce these risks significantly and help their dogs lead longer, more comfortable lives.

Routine vet check-ups, body condition monitoring, and lifestyle changes can go a long way in preventing the silent dangers of excess weight.

💡Remember: Helping your dog achieve a healthy weight isn’t about restriction—it’s about balance, enrichment, and care. Speak to your vet about a tailored nutrition and exercise plan, and consider signing up for a Pet Care Plan that includes routine check-ups, parasite prevention, and dietary guidance.
