Overweight pets are no longer a rare sight. From chunky cats struggling to groom themselves to dogs that pant heavily after a short walk, pet obesity has become a growing concern today.
Research from indicates that approximately 40% of adult cats and dogs worldwide are classified as overweight or obese. , in its report, adds, “Worldwide, studies estimate that up to 63% of pet cats and 59.3% of pet dogs are overweight or obese.”
This puts them at risk for serious health issues , diabetes, heart disease, and a shortened lifespan. While it’s easy to dismiss a pudgy pet as ‘cute’ or ‘well-fed,’ experts warn that this trend is often the result of human behaviour.
Dr Deepraj Prajapati, senior veterinarian at RD Pet Hospital Ambedkar Nagar, tells , “One of the most common mistakes is equating food with affection. Many pet parents show love by offering extra treats or human food, unaware that even small indulgences can lead to in animals. Another issue is misjudging appropriate portion size, owners often rely on visual estimation or outdated feeding guidelines rather than tailored advice from a vet.”
Lack of physical activity is another factor, he states. In urban households, especially, pets may not get enough structured play or walks, and their energy expenditure is significantly lower than what their diet accounts for. Weight gain can creep in slowly, and because owners see their pets daily, they may not recognise the changes until the issue becomes severe.
Commercial pet foods and treats can play a significant role in weight gain, particularly if feeding instructions aren’t interpreted correctly. “Many of these products market themselves as ‘healthy’ or ‘nutritionally complete,’ but the portion sizes recommended are often based on ideal conditions—not taking into account a pet’s age, activity level, or breed,” says Dr Prajapati.
He adds that treats are another overlooked source of excess calories. Some treats, even in small quantities, can add up to 15-20% of a pet’s daily calorie needs. And because they’re marketed as supplements or rewards, they’re often not factored into daily meal planning.
To avoid confusion, Dr Prajapati advises, it’s best for pet parents to work with a vet to determine accurate portion sizes and understand label claims critically. Caloric density and ingredient quality vary widely between brands, and what works for one animal may not be suitable for another.
In many cases, obesity in pets can be reversed through consistent dietary changes, increased physical activity, and ongoing monitoring. Dr Prajapati stresses, “However, it requires a committed and gradual approach. Crash diets or sudden exercise routines can be harmful, especially in older pets or those with underlying conditions.”
That said, there are situations where medical intervention is necessary. Dr Prajapati explains, “Hormonal disorders like hypothyroidism or Cushing’s disease can contribute to and make weight loss difficult without treatment. In such cases, medication, therapeutic diets, and regular veterinary check-ups become essential components of the weight management plan.”
The goal is to create a sustainable routine that supports the pet’s long-term health rather than focusing on short-term results.
