Chubby puppies always make us go “aww” when we see them, but obesity in dogs can lead to many serious consequences. Dog obesity is a common problem, especially among indoor dogs that get little exercise and are overindulged with food by their owners. Besides reduced mobility, obese dogs are also more prone to serious illnesses such as diabetes, arthritis, heart disease, and a shorter lifespan.
1. What is the ideal weight for a dog?
Each dog breed has a different standard weight. For example:
- Toy Poodle: 3–5 kg
- Corgi: 10–14 kg
- Golden Retriever: 25–32 kg
However, the most important indicator is the BCS (Body Condition Score), which applies to all breeds.
2. What is BCS? How to assess obesity in dogs

The BCS (Body Condition Score) for dogs uses a 1–9 scale:
- 1–3: Underweight
- 4–5: Ideal
- 6: Slightly overweight
- 7–9: Overweight → obese
Signs of an ideal BCS (4–5):
- Ribs can be felt easily with light pressure
- A clearly defined waist when viewed from above
- A slightly tucked abdomen when viewed from the side
Signs of BCS 7–9 (obesity):
- Ribs cannot be felt
- No visible waist
- Bulging or sagging abdomen
- Fat rolls around the neck
- Heavy, sluggish movement
3. Signs of dog obesity
1. Large or rounded abdomen
There is no visible curve behind the rib cage.
2. Thick fat deposits around the neck, shoulders, and back
3. Ribs cannot be felt even when pressing firmly
4. Heavy breathing when running or climbing stairs
5. Laziness and personality changes
Overweight dogs are usually less active and energetic.
