Surveys show that 50% of dogs and cats in the UK are currently overweight, which is defined as 15% over ideal bodyweight. Overweight pets are at higher risk of developing health problems such as heart disease, skeletal and breathing problems, skin disease, diabetes and arthritis.

Those extra little treats can really add up, and they don't give your pet the nutrition that it needs. Like people, pets don't necessarily like what is good for them! But it is not just overindulgence that can lead to overweight pets, some dog breeds are genetically inclined to obesity. These include such as the Labrador Retriever, Cairn Terrier, Long Haired Dachsund, Basset Hound, Cavalier King Charles Spaniel and Beagle. Neutering or spaying can increase a pet's propensity to gain weight also.

Dogs and cats have different kinds of weight problems. The risk of a dog becoming overweight increases throughout its life, while for cats the risk of becoming overweight increases after it is three years old but decreases after it reaches the age of six.

If you think your pet has a weight problem, here are some helpful tips:

• Consult your vet if you think that your pet is overweight - never try to plan a slimming programme yourself.
• If you can't feel your pet's ribs clearly visit the vet for a free weight check. Your vet will weigh your pet and conduct a simple test called a Body Condition Scoring System to enable him or her to make a visual and external assessment of your pet's weight.
• As in humans, successful weight loss is a gradual process - set realistic goals for your pet. If your pet is 25% overweight, it will probably take your pet one-quarter of the year to reach its target weight.
• If you have other pets in the house, don't feed them alongside your overweight pet - or closely supervise the feeding to avoid food stealing.
• If your pet is used to being fed treats, 'treat' with a portion of its daily food allocation or speak to your vet about appropriate calorie-controlled treats.
• Exercise can be key in effective weight loss. Work with your vet to develop an effective programme that works for both you and your pet! Start slowly and build up to two to three 15 minute sessions per day.
• Make exercise fun! As well as daily walks, try and encourage your dog to play fetching games. Cats can enjoy 'play hunting' toys to increase their exercise levels.
• Weigh your pet every two weeks to monitor its weight loss. Why not make a chart and attach to a pinboard/fridge to remind you of your pet's positive progress.
• Pay your pet extra attention during the weight loss period - subsititute food with love!
• Be sure that nobody is giving food to your pet, i.e. children or neighbours.
• Keep the pet out of the kitchen when food is being prepared, and feed your pet before you have your own meal.

If at any time you encounter problems, discuss them with your vet. If you are embarking on a weight loss programme for your pet, why not ask your vet if you qualify to enter the Hill's Pet Slimmer of the Year contest? It could be just the incentive you need.
