Causes, risks & what really helps

Overweight in dogs

Obesity in dogs is a widespread problem - and often harder to recognise than you might think. At first glance, anoverweight dog often simply appears to be "well-fed", but long-term obesity can have serious consequences for health, mobility and quality of life.


How can I recognise if my dog is overweight?

Not all weight gain is immediately visible. Typical signs of overweight in dogs are:

  • Ribs are no longer easily palpable
  • No recognisable waistline from above
  • Belly line hangs or runs straight
  • Your dog gets tired more quickly or is less active
  • Shortness of breath with little exertion

The Body Condition Score (BCS) provides a helpful guide. It rates your dog's body condition on a scale of 1 to 9. A healthy score is usually between 4 and 5.

If you are unsure whether your dog is overweight or how severe it is, ourveterinary nutritional counsellingat PERRO will be happy to help you with an individual assessment.

Causes & risks of obesity in dogs

Common causes of obesity in dogs

  • Too large portions of food
  • Lots of snacks & chews in addition to the main food
  • Lack of exercise
  • Castration (altered metabolism)
  • Age (lower energy requirements)
  • Hormonal diseases

Important: A dog can also become overweight even though it is fed little food if calorie requirements and food composition do not match.

Health risks

Adog that is overweight has a significantly increased risk of:

  • Joint problems & osteoarthritis
  • Cardiovascular diseases
  • Diabetes
  • Respiratory problems
  • Shortened life expectancy

How much should my dog weigh? (depending on the stage of life)

The ideal weight for dogs depends on the following factors:

  • Dog breed
  • Size of the dog
  • Age of the dog
  • Activity level
  • State of health

Rules of thumb:

  • Puppies & young dogs: even growth, no "flab"
  • Adult dogs: slim, well-muscled, visible waistline
  • Seniors: Slightly less muscle mass is normal, fat gain is not

If you want to put your dog on a diet, an individually determined ideal weight is particularly important. Ourveterinary nutritional counselling at PERROwill help you to determine the right target weight and find a diet plan that really suits your dog.

Individual support from our veterinary nutritional counselling service

Every dog is different - and many factors play a role in obesity in particular. In our veterinary nutritional counselling, we provide you with personal and professional support on the way to a healthy weight for your dog.

Among other things, our experts will support you with:

  • Assessment of the current body condition
  • Determining a realistic target weight
  • Selection of asuitable diet food
  • Creation of an individual feeding plan

Tips if you are switching to diet food but your dog is picky

Many dogs react sceptically to new food. This is how the changeover works:

  • Slow changeover over 7-10 days
  • Warm the diet food slightly
  • Add a little water or low-sodium bone broth
  • Stick to fixed feeding times
  • Do not give in immediately if the dog "goes on strike"

Important: No extras on the side, otherwise the diet food will lose its effect.
