As we are settling into work after the New Year, many of us start to think about exercising more and eating healthier, especially after indulging a little over the festive period. While we are often quick to notice changes in our own weight, when was the last time you checked your dogs weight?

Just like us, dogs can easily gain excess weight and obesity in dogs can come with problems. Extra treats, food dropped on the floor and shorter or fewer walks can all contribute to unwanted weight gain. That’s why, with National Obesity Awareness Week in full swing, we are taking a closer look at canine obesity, its risks and how natural light dog food can help your four-legged friend maintain a healthy dog weight.

How common is obesity in dogs?

Did you know that around 30% of dogs in the UK are overweight? Canine obesity is the most common nutritional disorder in dogs and in most cases, it is completely preventable.

Carrying excess weight can lead to health problems in dogs, including:

  • Increased pressure on joints, leading to joint pain and mobility issues
  • Added strain on the heart, lungs, liver and kidneys
  • Higher risk of illness and injury
  • Greater risk during anaesthetic and surgical procedures
  • Increased likelihood of cardio-respiratory disease, hormonal disorders, cancer, skin problems and even a shortened lifespan

If you are concerned about your dogs weight, always speak to your vet for professional advice.

What are the causes of obesity in dogs?

The main cause of dog obesity is consuming more calories than are being burned, with excess energy stored as fat. However, there are many different causes of obesity in dogs, including:

  • Sex
  • Current weight
  • Reproductive status (neutered or entire)
  • Food intake and treats
  • Lifestyle and exercise levels
  • Underlying medical conditions that reduce activity

Ultimately, overfeeding is the most common reason dogs gain weight. Many owners are unaware of how many calories their dog actually needs each day.

How much should I feed my dog?

At the Natural Dog Food Company, we provide clear feeding guides on all our dog food bags and on our website to help owners feed the correct amount.

  • 1-5Kg: 20-50g

How can I help my dog lose weight safely?

If your dog is overweight or obese, small, consistent changes can make a big difference.

  1. Review feeding habits
  • Follow feeding guides carefully
  • Avoid overfeeding
  • Split daily food into smaller meals to help your dog feel fuller for longer
  • Avoid feeding too late in the evening as dogs burn fewer calories while sleeping
  1. Increase exercise gradually
  • Start with short, gentle walks and build up gradually
  • Exercise alongside your dog, it is great motivation for both of you
  • Try canine activities like agility or flyball once your dogs fitness improves
  1. Regular vet check ups
  • Many vets offer free weight checks
  • Your vet can track progress and rule out any underlying health conditions affecting weight
  1. Weigh your dog at home

You can easily monitor your dogs weight between vets visits

  • Weigh yourself
  • Pick up your dog
  • Weigh yourself again
  • Subtract your weight from the combined total
  1. Choose the right dog food to lose weight
  1. Reduce treats
  • Cut back on treats
  • Swap high-calorie treats for healthier options like carrot sticks or cucumber

What are the benefits of a healthy weight for dogs?

As your dog loses weight, you will likely notice:

  • Increased energy
  • More enthusiasm for walks
  • Improved mobility
  • Greater interest in play and interaction

So why wait? Start today

Exercise together to keep your dog healthy this National Obesity Awareness Week

National Obesity Awareness Week is the perfect time to build healthier habits. Grab the lead, wrap up warm and enjoy a family walk around the neighbourhood. Get the kids out on their bikes or scooters and make exercise a shared routine.

Dogs need between 20 and 60 minutes of exercise a day depending on breed, size and health. If your dog is overweight, start slowly with shorter, more frequent walks to avoid strain.

Regular exercise and a balanced diet are the best ways for both humans and dogs to shed excess weight and the benefits are long lasting.

Your dog may feel just as reluctant as you to head out on cold winter evenings but those extra pounds can lead to serious health problems if ignored. Even a short daily walk can make a huge difference to your dogs wellbeing. Obesity in dogs is not permanent and can be prevented.

If in doubt, always consult your vet for tailored exercise and feeding advice.
