Obesity in Dogs and Cats: How to Identify, Prevent and Treat

The Silent Problem on the Scale

Obesity is now one of the most common health problems in dogs and cats — and it often goes unnoticed by pet owners. According to veterinary studies, more than 50% of pets seen in clinics are overweight or obese. The issue is that excess weight is not just an aesthetic concern: it affects joints, internal organs, the cardiovascular system, and the animal's overall quality of life.

How Do I Know If My Pet Is Overweight?

The most reliable assessment is performed by a veterinarian using the Body Condition Score (BCS), a scale from 1 to 9 where the ideal range is between 4 and 5. At home, you can do a quick check:

  • Ribs: you should be able to feel the ribs with gentle pressure, but they should not be visible
  • Waist: viewed from above, the body should have a slight tuck behind the ribs
  • Abdomen: from the side, the belly should tuck up slightly toward the hind legs

If the ribs are hard to feel, the waist is not visible, or a prominent belly is evident, it's time to talk to your veterinarian.

Main Causes of Obesity in Pets

CauseDetails
OverfeedingPortions larger than needed
Frequent treatsIncluding human food scraps
Sedentary lifestyleLack of walks and playtime
Neutering without diet adjustmentMetabolism changes after the procedure
Hormonal diseasesHypothyroidism, hyperadrenocorticism
GeneticsSome breeds are predisposed (Labrador, Beagle, Persian)

Consequences of Excess Weight

Obesity in animals is associated with several serious conditions:

  • Diabetes mellitus — especially in cats
  • Joint diseases — arthritis and dysplasia worsen with weight
  • Respiratory problems — especially in brachycephalic breeds
  • Liver disease — feline hepatic lipidosis is a medical emergency
  • Reduced life expectancy — studies show a reduction of up to 2 years in obese dogs

How to Help My Pet Lose Weight

Weight loss in pets must be supervised by a veterinarian. Very restrictive diets can be dangerous, especially in cats. In general, the process includes:

  1. Full veterinary evaluation to rule out hormonal causes
  2. Choosing a weight-control diet or prescription food
  3. Strict portion measurement using a measuring cup or scale
  4. Eliminating high-calorie treats — replace with vegetables like carrots and cucumber (for dogs)
  5. Gradually increasing physical activity — longer walks, interactive play
  6. Monthly weigh-ins to track progress

Prevention: Easier Than Treatment

Maintaining a healthy weight from puppyhood or kittenhood is much simpler than treating obesity. Regular veterinary check-ups, an appropriate diet for each life stage, and a routine exercise schedule are the pillars of a long and healthy life for your pet.

If you have questions about your pet's weight or need a personalized nutrition plan, schedule a consultation. Taking care of your pet's weight is one of the greatest acts of love you can show them.
