Millions of pets have lost weight with Hill's

Feeding is one of the ways that pet owners show their love and establish an emotional bond with their pet. But feeding and indulging your pet too much can lead to weight problems that you might not notice at first.

Around 55% of dogs and cats are overweight, but 90% of pet owners with an overweight pet don’t realise it. It can be hard to recognise weight issues, but even a few extra pounds can put pets at risk for health problems, like diabetes, arthritis and reduced mobility.

Through intensive research on dog and cat biology, Hill’s has identified some of the contributing genetic factors of obesity and formulated nutrition to help pets maintain a healthy weight — so it’s easy to feed the love, while helping your pet lose weight.

Many people are unaware of what being overweight looks like

Like humans, weight gain can happen gradually for pets, which makes it difficult to tell when your dog or cat has reached a point where their weight has become a health risk. Diabetes, arthritis and fatigue could all be related to weight gain in pets.
