Although some diseases can cause obesity, the main reason that pets become fat is because the food they eat contains more energy than they use up. This means that if pets eat too much or do not do enough exercise, they may become obese.

Studies from various parts of the world have estimated that between 22 and 44 per cent of dogs are overweight and these figures are similar for cats. 

Just a few examples of potentially serious medical conditions associated with obesity in pets include diabetes mellitus, orthopaedic disease, heart disease, respiratory disease, high blood pressure, skin diseases and cancers.

It is likely that obesity also affects a pet’s ability to perform a range of natural behaviours. For example, a fat pet may not be able to exercise without experiencing respiratory problems or heat stroke.

For dogs and cats there are a few simple checks you can do which, if carried out regularly, can help you to prevent your pet from becoming obese:

 You should be able to see and feel the outline of the ribs without excess fat covering.

 You should be able to see and feel your pet’s waist and it should be clearly visible when viewed from above.

 The belly should be tucked up when viewed from the side.

If it does not pass all three checks above, or if you are in any doubt about your pet’s weight, consult your vet.

They will be able to give your pet a health check and if necessary will recommend a weight reduction programme.  This will most likely involve making changes to your pet’s diet and making recommendations about exercise and activity.

Making these changes will help prevent it from gaining excess body fat and keep healthy and happy.
