About the Programme

Now in its fifteenth year, the Hill’s Pet Slimmer of the Year competition takes place to raise awareness of the dangers of pet obesity and show what a difference healthy weight loss can make to an overweight pet.

Congratulations to Buddy Knoesen who was chosen as the 2011 winner by public voting. He was one of nine dogs and one cat in the running; the ten finalists below had lost, on average, almost 30% of their bodyweight and each has an inspiring weight loss story to tell. Read more about it on their profile pages below.  

The Hill’s Pet Slimmer programme, which is run by hundreds of veterinary clinics in South Africa and Namibia, combines the clinically proven weight loss food with regular weigh-ins and expert advice. It has proven to be a successful formula for thousands of cats and dogs. Participating practices in South Africa are detailed on our clinics page. For advice on how to help your pet rediscover its sleeker silhouette, speak to your vet or call us toll free on 0800228783.

In the last 5 years, the Hill`s Pet Slimmer programme has helped close on 10,000 pets live a happier, healthier, slimmer life.

Over the past 5 years, our 300 competition entrants have lost over 2,000 kgs – that’s the weight of a rhinoceros!

Our biggest loser lost 26 kgs which was more than half of her total body weight (54%).

We hate to admit it, but 63% of our Pet Slimmers are female.

We’ve had more pets on the programme called Jessie, Bella and Sasha than any other name.

If you are a Dachshund and Labrador just sign up now. They are the leading overweight breeds by far.
